Synthesis and characterization of diaryl pyrazole-4-carbaldehyde semicarbazones metal complexes

Abstract

Four heterocyclic ligands [1,3-diarylpyrazole-4-carbaldehyde semicarbazones] and their metal complexes with d-block transition elements (Cu2+, Ni2+, CO2+, Pb2+, Zn 2+ and Fe2+) have been synthesized and characterized through elemental analysis and spectroscopic techniques viz., FTIR, 1H NMR and mass spectra.
