N2 - Two new five coordinated Cu(II) complexes, Cu(L)Cl-2,CH3OH (1) and Cu(L)Br-2 (2) derived from the flexidentate ligand (L), 2-pyridinealdazine, have been synthesised and characterised by spectroscopic and electrochemical studies. Single crystal structures of the complexes were determined. Crystal structures of both the complexes contain monomeric entities of five coordinated copper(II) ions where the Schiff base ligand, 2-pyridinealdazine, acts in a tridentate fashion. The central part of the ligand in complex 2 is disordered over two positions: N8-N9 make up the major position and N8A-N9A make up the minor position. (c) 2006 Elsevier B.V. All rights reserved.
