Synthesis, structural and luminescence studies of some zinc complexes having pyrazole and carboxylate ligands

Some zinc (II) complexes of the type [Zn(PziPr2H)(μ-PziPr2)(RCOO)]2 have been prepared and structurally characterized by different techniques including single crystal X-ray. The X-ray studies suggested that all these complexes are binuclear with tetrahedral geometry around each zinc center and having hydrogen bonding between hydrogen atom of pyrazole (N-H of pyrazole) and unbonded oxygen atom of carboxylate ions.
