:Talk:Cacodyl oxide

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.

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