摘要：

The reaction of the ligand 3-(6-methyl-2-pyridyl)-5-(2-pyridyl)pyrazole (HL) with Cu(NO3)(2) (.) 3H(2)O gives a complex of formula [Cu4L4(NO3)(3)] (NO3), which has been characterised by elemental analyses, infrared and electronic spectroscopies and single-crystal X-ray diffraction. The molecular structure of this complex is tetranuclear. The Cu2+ ions are linked to four ligands, forming a macromolecular cyclic system. The co-ordination geometries of the Cu(II) are square pyramid. The formation of this complex implies a control of nuclearity by steric hindrance. (C) 2003 Elsevier Science B.V. All rights reserved.
