Abstract

Four heterocyclic ligands [1,3-diarylpyrazole-4-carbaldehyde semicarbazones] and their metal complexes with d-block transition elements (Cu²⁺, Ni²⁺, Co²⁺, Pb²⁺, Zn²⁺ and Fe²⁺) have been synthesized and characterized through elemental analysis and spectroscopic techniques viz., FTIR, ¹H NMR and mass spectra.
