A new cyanato-bridged polymeric complex [Cd3(NCO)6(NH2CH2C5H4N)3]n with a zig–zag ladder shaped structure

A new cyanato-bridged polymeric complex [Cd3(NCO)6(NH2CH2C5H4N)3]n has been synthesized and characterized by X-ray crystallography. There are three cadmium atoms, three chelated 2-(aminomethyl)pyridine and six end-on bridging cyanato groups in the asymmetric unit. Each Cd atom is bonded to one chelated C5H4NCH2NH2 base and four μ2-NCO groups in a distorted octahedral environment. Three such independent CdN6 octahedra share their bridging edges to produce a zig–zag ladder shaped polymeric network extending along a.
