摘要：

The copper(II) complex [Cu(teta)N(CN)2](ClO4)H2O (teta = 5,7,7,12,14,14- hexamethyl-1,4,8,11-tetraazacyclotetradecane) has been synthesized and the crystal structure was determined by single-crystal X-ray diffraction. Crystal data: C18H38ClCuN7O5, monoclinic, space group P21/n, a = 8.796(3), b = 11.885(4), c = 23.054(9) , b = 97.540(4)o, V = 2389.3(15) 3, Mr = 531.54, Z = 4, Dc = 1.478 g/cm3, F(000) = 1124, ?= 1.070 mm-1, the final R = 0.0566 and wR = 0.1162 for 4749 observed reflections (I > 2s(I)). The center copper ion is coordinated by five nitrogen atoms in a square pyramidal geometry, with four from the macrocyclic ligand teta and the other one from a nitrile nitrogen atom of dicyanamide which is coordinated to the metal atoms as uni-dentate manner via nitrile nitrogen atom.
