Structure of methylphenylarsinic acid showing intermolecular hydrogen-bonding.[1]
Arsinic acids are organoarsenic compounds with the formular R2AsO2H. They are formally, but not actually, related to arsinic acid, a hypothetical compound of the formula H2AsO2H. Arsinic acids are monoprotic, weak acids. They react with sodium sulfide to give the dithioarinates R2AsS2Na. [2] Arsinic acids are related to phosphinic acids (R2PO2H.).
Well known arsinic acids include diphenylarsinic acid and cacodylic acid, R2AsO2H (R = Ph, Me, respectively).[3]
