Synthesis and structural characterization of the molecular loop [cis-Mo2(N,N′-di-p-anisylformamidinate)2]2(O2C-CHî˜ Cî˜ CH-CO2)2

The molecular loop [cis-Mo2(DAniF)2]2(O2C-CHCCH-CO2)2, in which two quadruply bonded Mo2 4+ units are linked by two chiral allene-1,3-dicarboxylate ligands of opposite optical configuration, has been synthesized and characterized by X-ray crystallography and electrochemistry.
