A square-pyramidal Ni(II) complex (1) with the composition [NiL(HL')]CIO4 center dot H2O was synthesized in the reaction of nickel(II) perchlorate and 2[2-(diphenylphosphino)benzylidene]-1-phthalazinylhydrazone (HL). The coordination surrounding the Ni(II) ion consist of a PNN coordinated deprotonated HL ligand and its corresponding oxidation product phosphine oxide HL' coordinated via two nitrogen atoms of the hydrazinophthalazine moiety. The structure of Ni(II) complex 1 was determined by X-ray analysis, IR spectroscopy, elemental analysis and magnetic measurements. In the reaction of copper(II) perchlorate with HL, a binuclear phthalazine bridged Cu(I) complex (2) was obtained with the composition [Cu-2(HL)(2)](ClO4)(2)center dot C2H5OH. The structure of Cu(I) complex 2 was determined by X-ray analysis, IR and NMR spectroscopy, elethental analysis and magnetic measurements.
