摘要
Three new copper(II) complexes of formula [Cu(2,2'-bpy)(Phmal)(H2O).2H(2)O (1), [{Cu(2,2'-bpym)(Phmal)}](n) (2) and [{Cu(phen)(Phmal)}](n).3nH(2)O (3) (Phmal = phenylmalonate- 2,2'-bpy = 2,2'-bipyridine; 2,2'-bpym = 2,2'-bipyrimidine; phen = 1,10-phenanthroline) have been prepared and their structures determined by X-ray diffraction techniques. Complex 1 is mononuclear whereas 2 and 3 are uniform chain compounds. The copper atoms in 1-3 are distorted square-pyramidal: two nitrogen atoms from the bidentate nitrogen heterocycle and two carboxylate oxygen atoms from the phenylmalonate ligand build the equatorial plane; the axial position is filled either by a water molecule (1) or a carboxylate oxygen atom from another pheny1malonate group (2 and 3). The values of the intrachain copper-copper separation through the phenylmalonate-carboxylate bridge in the
