Abstract:
The reactions between Cd(OAc)2/Cu(NO3)2 and mixed ligands (2,3-pyrazinedicarboxylic acid (pzdc) and N-donor ligands) under different reaction conditions give the three title complexes 1, 2 and 3. There is a (4,8) net 2D network structure and a rectangular grid network structure in the cadmium complexes [Cd(pzdc)(phen)] · H2O (1) and Cd2(pzdc)2(4,4′-bpy)(H2O)2 (2), respectively. The complex [Cu4(pzdc)4(phen)2(H2O)4] · 10H2O (3) has a 1D zigzag chain structure. The influences of coordination modes of the pzdc ligand and N-donor ligands on the superstructural diversity have been discussed. Complexes 1 and 2 exhibit strong fluorescent emission bands in the solid state at room temperature. The EPR spectrum of 3 is typical for a square-pyramidal geometry of copper (II) ions. © 2007 Elsevier Ltd. All rights reserved.
