Synthesis, spectral characterization and crystal structure of copper(II) complexes of 2-hydroxyacetophenone-N(4)-phenyl semicarbazone
TL;DR: In this article, the tridentate character of the semicarbazone is inferred from IR spectra based on EPR studies, the spin Hamiltonian and bonding parameters have been calculated.

Synthesis, characterization and physiochemical information, along with antimicrobial studies of some metal complexes derived from an ON donor semicarbazone ligand
TL;DR: Eight new transition metal complexes of benzaldehyde-N(4)-phenylsemicarbazone have been synthesized and characterized by elemental analyses, molar conductance, electronic and infrared spectral studies, and the metal ligand bonding parameters evaluated showed strong in-plane sigma bonding and in- plane pi bonding.
