摘要：

The copper(II) complexes [Cu(PyTT)(2)(H2O)](NO3)(2) (A) and [CuCl2(mu-PyTT)(2)CuCl(H2O)]Cl . 3H(2)O (B) were synthesized and characterized by single crystal X-ray diffraction, IR spectroscopy, UV-Vis-NIR diffuse reflectance and magnetic susceptibility measurements. In the mononuclear compound A the copper ion is in a distorted square pyramidal geometry, with the equatorial plane formed by two thiazoline nitrogen atoms, one imino nitrogen atom and one water molecule, whereas the axial site is occupied by one imino nitrogen atom. The compound B is dinuclear and both Cu(II) centres present environments that can be described as slightly distorted square pyramidal geometries. The observed molar magnetic susceptibility for A (mu = 2.13 BM) allows to exclude metal-metal interactions, supporting a monomeric structural formulation for this compound. In compound B, magnetic susceptibility measurements in the temperature range 6.2-288 K show an intradimer anti ferromagnetic interaction (J = -11.8 cm(-1)). (C) 2004 Elsevier B.V.
