摘要：

A new complex of formula [Cu(dach)(2)(CCl3CO2)]CCl3CO2 (dach = 1,4-diazacycloheptane) has been synthesised and its crystal structure determined by single-crystal X-ray diffraction. The crystal structure contains two independent copper(II)-centred cations (one disordered) and two trichloroacetate ions. Both copper(II) atoms are pentacoordinate. The chelated 1,4-diazacycloheptane moieties are in a double boat conformation and represent the first structurally characterised example of a trans configuration for two such ligands at a metal centre. The compound was also characterised by IR, electronic and EPR spectra, cyclic voltammetry, and magnetic susceptibility studies. (C) 2000 Elsevier Science Ltd. All rights reserved.
