Synthesis, Molecular Structure, and Spectral Characteristics of Lead(II) Complexes with 1,5-Dimethyl-4-[2-(3-methyl-5-oxo-1-phenyl-1,5-dihydro-4H-pyrazol-4-ylidene)hydrazinyl]-2-phenyl-1,2-dihydro-3H-pyrazol-3-one

Abstract

Pb(II) cations form complexes with 1,5-dimethyl-4-[2-(3-methyl-5-oxo-1-phenyl-1,5-dihydro-4H-pyrazol-4-ylidene)hydrazinyl]-2-phenyl-1,2-dihydro-3H-pyrazol-3-one (HL) in an aqueous-ethanolic solution. The C42H41N13O9Pb2 compound has been isolated in the crystalline state and its spectral characteristics have been determined. As per X-ray diffraction analysis data, it is a cocrystallizate of the Pb2L2(OH)2·(H2O)2 binuclear complex and the PbLNO3 dimeric associate. According to the simulation using the Bader method, the lead cations both in the binuclear structure and in the dimeric associate have not interacted.
