Talk:Cacodyl oxide

Composition and structure
The article contradicts itself. The main body of text gives the molecular formula as C4H12As2O, with the structure Me2As−O−AsMe2.

The infobox, however, states the molecular formula as C4H8As2O3, with the structure MeC(=O)As−O−AsC(=O)Me shown as an image.

Both cannot be correct. I expect the former is correct, by analogy with cacodyl, Me2As−AsMe2.

I'll look for an authoritative source to confirm the correct structure and composition, but if any other chemical Wikipedians want to do so too, that'd be great.

 * Here we go: cacodyl oxide on ChemID+ has the structure as (Me2As)2O.

Crystal structure
I couldn't find free cacodyl oxide in the CSD, but it is present as a ligand in (at least) the following structures:


 * OKUVIZ
 * WOMPIX
 * WOMPUJ
 * WOMQEU
