Isolation and Properties of a Chain of Cyano-Bridged Complex {LCuII(μ-CN)}n With Triazenido Ligand and a Cyano-Bridged Mixed-Valence Complex {CuIICuI(μ-CN)3}n
摘要:
One reaction of 1-[(2-carboxymethyl) benzene]-3-[2-pyridine] triazene (HL) with CuCl2 center dot 2H2O, and NaCN gives a chain of cyano-bridged complex {LCuII(mu-CN)}n 1 and a cyano-bridged mixed-valence complex {CuIICuI(mu-CN)3}n 2, respectively. The X-ray crystal structures of both complexes have been obtained. Magnetic studies indicate significant antiferromagnetic coupling between the copper(II) centers for complex 1, with coupling constants (J) of 129.6 cm-1.
