Synthesis and structure of a novel heterotrimetallic helical chain polymer {O2MoS2(CuCN)Ni(1,10-phen)2}n

A novel 1-D heterotrimetallic polymer {O2MoS2(CuCN)Ni(1,10-phen)2}n containing cyanide ligands was synthesized and characterized by single-crystal X-ray diffraction studies. This compound can be described as an “8”-like helical chain that the CN− ligands are bridged between Ni and Cu atoms while the μ2-S and μ2-O atoms are bridged between Mo and Cu and Mo and Ni atoms, respectively.
