Merge proposal with Oxo wall[edit]
The section in this article on the "oxo wall" is better developed than the entire article on oxo wall. While temporarily topical, oxo wall is likely to be a subsidiary aspect of oxo ligands. --Smokefoot (talk) 18:26, 16 January 2011 (UTC)
Electron counting and bonds[edit]
I should start by saying that I might very well be wrong (and if so then feel free to ignore me), but I have some issues with the complexes shown here. There are several examples of oxygen forming 3 bonds to a metal, which in my experience is an unusual depiction. Also the election counting bothers me, I accept that permanganate is in oxidation state VII, but that's not the same as it having a formal 7+ charge, so I don't think it's really d0 (or indeed ionically bonded as that would suggest). This augment spills over to the molecular orbital diagram, which seems to be showing covalent-style bonding between O2- and Mn+ ions. As I said I may well be wrong, my inorganic chemistry is somewhat patchy, but I figured there's no harm is asking. Project Osprey (talk) 21:06, 15 April 2013 (UTC)
- Good points. Depicting metal oxides with triple bonds is a matter of taste, but the recent trend among inorganickers is to draw it that way to emphasize the sigma and two pi-interactions. CO and [[acyl#Acylium cations, anions, and radicals|acylium cations have a similar issue. Not all metal oxo's have triple bond character, but most do. The ones that dont often obey the 18e rule. One could argue that we should show a positive charge or a partial positive charge on the O, but then the drawings get too messy. Others might have alternative views. --Smokefoot (talk) 00:33, 16 April 2013 (UTC)
- No, it can be explained by analyzing the molecular orbital diagram. Metal-Oxo's can be singly, doubly, or triply bonded. There are examples of each in the literature. Pwnsey (talk) 05:17, 15 March 2015 (UTC)
Silicate minerals do not contain oxo ligands[edit]
Silicate minerals comprise 90% of the Earth's crust. However, it's not accurate to say these minerals contain oxo ligands in the coordination chemistry sense. Rather, the silicon and oxygen are bound together to form the silicate anion, which acts as the ligand towards metals that include transition metals Aherthabey talk 21:34, 15 May 2021 (UTC)
