摘要

The synthesis, structure, and physical properties of a series of mononuclear complexes viz. [Cu(L)2] 1, [CuL2(CH3O)(2)] 2 and [Zn(L)(2)] 3 (where L = 1-Phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP)) are presented. The complexes were characterized by elemental analysis, IR and electronic spectroscopy (1 and 2), magnetic measurements at room temperature (1 and 2) and thermogravimetric analysis. The structures of all the three complexes were determined by single crystal X-ray diffraction studies. The coordination geometry around complexes CuL2 (1) and ZnL2 (3) is slightly distorted square planar while the geometry around Cu(II) of [Cu(L)(2)(CH3O)(2)] (2) is distorted octahedral with four oxygen atoms of two PMBP ligand occupying the equatorial positions and two methanol molecules occupying the two axial positions.
