Synthesis,structure and properties of a one-dimensional coordination polymer containing both dicyanamide and ethylenediamine
Abstract:The nickel(II) complex [Ni(en)2{N(CN)2}]ClO4 1 (en?=?ethylenediamine) has been synthesized and its structure determined. The complex forms a one-dimensional chain structure via the bidentate bridging ligand dicyanamide. A two-dimensional network is formed via interchain hydrogen-bond interactions. The magnetic properties of the compound (5–300?K) show the existence of weak antiferromagnetic exchange interactions between paramagnetic centers along chains.
Keywords:Crystal structure  Dicyanamide  Hydrogen bonding  Nickel complex
