Re: How to nip erroneous content in the bud?

Yeah, the textbook is the tenth edition from 2011. I did some digging and it looks like the authors were using an older set of IUPAC recommendations - I found a version from 1999 that wants the anionic ligands before the neutral ones. IUPAC updated things in 2005 to the ligand placement not depending on charge.

Ha! I figured it was something like this. Do you know what edition/year of the book you were looking at? If I understand correctly, it was pre-2012, and so its likely that rules have changed since the book was published. I wonder if the current edition has the same rules.

Regardless, I think it is better to go with current IUPAC rules. As far as I understand, most manufacturers and publishers prefer IUPAC nomenclature, right?

However...I can see how this could mess someone up (like you) if you have assignments that are graded based on these "alternative facts" (lol). Perhaps we should identify the pages and just let people know about it if they have forked or transcluded content in their own course shells. Thoughts?


Re: How to nip erroneous content in the bud?

smmuller@...
 

Oh no, I thought that looked familiar. I made the graphic for my 2012 Chemistry 2C extra credit assignment, and another student wrote the text. The original page was named "Nomenclature for Coordination Complexes" but I'm not sure where exactly it is now on the site.

Our source was the course textbook:
  • General Chemistry: Principles and Modern Applications, by Petrucci et. al.   
  • Chapter 21: Complex Ions and Coordination Compounds    
  • Section 21-3: Nomenclature    
  • Page 915
Rule 5 on that page says:
When we write the formula of a complex, the chemical symbol of the metal center is written first, followed by the formulas of anions and then neutral molecules. If there are two or more different anions or neutral molecules as ligands, they are written in alphabetical order according to the first chemical symbols of their formulas. Thus, in the formula of the tetraaminechloronitrito-N-cobalt(III) ion, Cl- precedes NO2-, and both are placed ahead of the neutral NH3 molecules: [CoCl(NO2)(NH3)4]+.
But the page starts with the caveat that "Even today, usage varies somewhat. Our approach will be to consider a few general rules," so maybe the authors had a style they liked that wasn't completely standard? (Or we could have misinterpreted something; it's been a while since I took the class.)

ok. If they don't get back, we can go to their programmer with whom we work.

I added the comma to the URL (and also noticed that the apostrophe in "Mary's" had been removed, so I added it back). The page URLs are now identical, but the annotations are still missing. I have submitted a ticket to the Hypothesis team to see if it is a problem on their end.

Yeah, they didn't want to write down Creative Commons CC BY (according to Cable Green), but this was the intent. The way I think they interpret this is "exercise _any_of_the_rights_ under
copyright conditioned only on the requirement that attribution be given as directed by the copyright owner. " Means the only restriction is the attribution. I disagree with that definition as a whole, but it is how they defined in their RFP.


Re: Hypothes.is annotations not visible even though public

Delmar Larsen <dlarsen@...>
 

That is ok. It just said the page existed previously.

The comma appears in the title of the course shell, but not in the URL.
When I went to add the comma to the URL, I got the following warning, which concerned me and so I did not commit the change:

The specific language in the RFP is

Open textbook means a textbook that

royalty-free, perpetual, and
irrevocable license to the public to
exercise any of the rights under
copyright conditioned only on the
requirement that attribution be given as
directed by the copyright owner. An
open textbook resides in the public

If adding a comma in the title fixes it, then go with that for now. I need to figure out how the canonical tag works.

Wow... so do I understand this correctly? The Dept of Ed wants it to be ok for others to use LibreTexts content for COMMERCIAL purposes? This is the CC-BY license description I found at this website (click). It seems to me that -SA-NC appendages would be appropriate, no?

CC BY: This license lets others distribute, remix, adapt, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.

It seems to be most, if not all, pages in the Saint Mary's course shell. One of my faculty suggested that the problem is "Essentially, the old URL contained the comma after Saint Marys College before Notre Dame (which in URL code is a "%2C"). The new URL no longer has the comma."

Edited

This was the message I got from Steve Contakes (who is brilliantly detail focused). If we can get a list of pages, we can correct the error on all pages, unless you have a better suggestion.
Thanks!

Kathryn,
 
I found another error on the site. While using Inorganic Syntheses to write problems for the nomenclature section I noticed that the formulae there and just about everywhere else didn't agree with the rules for writing of formulas for coordination compounds given on several Chem.libretexts pages.  From the pages on our site it looks like we were misled by some students at UC Davis who wrote an article on the site saying that anionic ligands should be placed before neutral ones and then backed it up by a snappy graphic. 
 
I am a bit ashamed to admit that I looked deeply enough into the nomenclature rules to say this but it turns out that not only is there is no such rule, the IUPAC red book expressly repudiates the practice:

IR-9.2.3.1 Sequence of symbols within the coordination formula 

(i) The central atom symbol(s) is (are) listed first. 

(ii) The ligand symbols (line formulae, abbreviations or acronyms) are then listed in alphabetical order (see Section IR-4.4.2.2).5 Thus, CH3CN, MeCN and NCMe would be ordered under C, M and N respectively, and CO precedes Cl because single letter symbols precede two letter symbols. The placement of the ligand in the list does not depend on the charge of the ligand.

 
The error persists on the following chem libre pages, possibly among others:

Re: How should we license figures created for LibreTexts construction? #Figures #Licensing

Delmar Larsen <dlarsen@...>
 

Yeah. There is a requirement from the Dept. of Ed. grant for it to be CC BY. if the image is created for this grant, then that is the preferred license. If content is remixed from other sources, then this doesn't apply.


Re: How to nip erroneous content in the bud?

Delmar Larsen <dlarsen@...>
 

If the content was transcluded or forked, then we can check the meta-tags for the source page ID. I have dreams of making this a bit clearer so we can see how content propagates through out our libraries. But, it is not at the top of our queue.

Which page and image needed updating?

How to nip erroneous content in the bud?

Kathryn Haas
 

One of our team has found some erroneous content, including figures, on Libretexts. Is there a simple way to find and replace any propagation of these errors on other pages (aside from a good old keyword search)?


How should we license figures created for LibreTexts construction? #Figures #Licensing

Kathryn Haas
 

I noticed that an attribution place holder has been added to Figure templates. So far, I've just left all new content without specific license because I wasn't sure.

I hate to open up a can of worms, but is there a preferred license to use for figures created specifically for construction efforts? Or is it simply up to individual authors?


Re: Hypothes.is annotations not visible even though public

Delmar Larsen <dlarsen@...>
 

Which page(s) specifically. We added a "canonical" tag so to the hypothesis to address moving of pages (e.g., renaming). But, we should confirm this.


Re: Hypothes.is annotations not visible even though public

Kathryn Haas
 

Delmar,
Several faculty at Saint Mary's, including myself, are currently plagued by this same issue. It seems that some URL's have been changed (although I haven't changed them) and hypothes.is has lost track of the page and cannot link the annotations. It would be helpful if this could be fixed. Can you help?
