摘要

Three new transition metal tricyanomethanide complexes[Cu(dpyam)(tcm)2](1),[Cu(dpyam)(tcm)(OAc)](2)and Zn(dpyam)2(tcmh(3)were synthesized and characterized by single crystal X-ray diffraction analysis.In 1 each copper(Ⅱ)atom is coordinated to three tcm anions and one dpyam molecule to form a square pyramide geometry.In 2 the coordination geometry around the central metal is also square pyramidal,and each copper atom is surrounded by two tcm anions,one dpyam ligand and one OAc.Both 1 and 2 display aμ1,5-tcm bridged infinite chain structure.In 3 each zinc(Ⅱ)atom is coordinated by two tcm anions and two dpyam molecules to form a distorted octahedral geometry.Different from the former two complexes,3 shows a mononuclear structure.Magnetic susceptibility measurement in the range 2-300 K indicates that there are weak antiferromagnetic couplings between adjacent copper(Ⅱ)ions in 1(J=-0.03 cm-1)and 2 (J=-0.11 cm-1)respectively.
