ACM-12 is a novel organoarsine oxide metal-organic framework (MOF), prepared using carboxylate functionalized triarylarsine oxide ligand coordinated to Co(II) nodes. The ligand is coordinated to the Co(II) nodes through both the carboxylate functional groups and through the oxygen bound to the arsenic. The coordination of the oxide oxygen to the metal node opens the arsine center to nucleophilic attack due to the formal positive charge on arsenic. The post synthetic modification of ACM-12 with carbon nucleophiles allows for Wittig reaction analogues within the MOF.
