| Description |
The syntheses and characterization of six copper(II) complexes of 2-benzoylpyridine benzhydrazone in the form of [Cu(BPB)(2)], [Cu(BPB)Cl]center dot H(2)O, [Cu(BPB)Br], [Cu(2)(BPB)(2)](ClO(4))(2)center dot 4H(2)O, [Cu(BPB)N(3)]center dot H(2)O, and [Cu(BPB)NCS]center dot H(2)O center dot CH(3)OH are reported. The analytical methods used for the characterization of complexes include partial elemental analyses, IR, electronic and EPR spectra, conductivity measurements, magnetic susceptibility measurements and single crystal X-ray diffraction. From the crystal structure, it is clear that the hydrazone adopts the E conformation about the azo bond to attach to the metal through the N(py)-N(azo)-O chelating system. In the EPR spectra of complexes in DMF at 77K four hyperfine quartets in the parallel region could be resolved and a half field signal is observed at 1500G for complex [Cu(2)(BPB)(2)](ClO(4))(2)center dot 4H(2)O in polycrystalline state at 298 K which gives evidence for its binuclear nature indicating a weak interaction between the two Cu(II) ions.
