Why does Mn-CO transition-state optimization converge to an unphysical 3.2 Å distance in Gaussian?
I need some help understanding the origin of an unusual behavior in my transition-state optimization. I am studying a manganese (Mn) metal complex coordinated to three CO ligands. It is known that Mn ...

Is hexaamminecobalt(III) chloride thermodynamically stable in pure water?
It is often said that "while cobalt(III) per se is strongly oxidising, hexamminecobalt(III) chloride is stable, even in concentrated hydrochloric acid, due to the strong donor properties of the ...

Does DeepMind's new protein folding software (AlphaFold) also work well for metalloproteins (proteins with metal cofactors)?
(1) Commonly, the metal is at the active site which needs the most prediction precision.
(2) Typically, there is only one (or a few) metals in a protein, which contains far more other atoms. So, the ...

How many spin states do Cu+ and Cu2+ have and why?
I know an electron can have two spin states, "spin up" and "spin down", but recently I was asked how many spin states do $\ce{Cu^+}$ and $\ce{Cu^{2+}}$ have, and why? Does anyone ...

Predicting magnetic moment of a metal complex computationally
Recently, for entrance exams, I have been dealing with a lot of weird compounds. One of them is $\ce{K3[Mn(CN)6]}$.
The objective was to predict the magnetic moment of the above complex.
I predict ...
