Electrical Properties of Cu-Based Coordination Complexes: Insights from In Situ Impedance Spectroscopy.

This study examines the influence of ligand design on the structural, optical, and electrical properties of copper-based coordination complexes. Ligands HL and HL were synthesized via the reaction of 5-nitrosalicylaldehyde with 2-hydroxy- or 4-hydroxybenzhydrazide. HL was obtained from the reaction of carbohydrazide and salicylaldehyde, while HL was prepared by condensing 4-methoxysalicylaldehyde with thiocarbohydrazide.

Impedance Spectroscopy as a Powerful Tool for Researching Molybdenum-Based Materials with Schiff Base Hydrazones.

Molybdenum coordination complexes are widely applied due to their biological and pharmacological potential, as well as their performance in different catalytic processes. Parent dioxidomolybdenum Schiff base complexes were prepared via the reaction of [MoO(acac)] with a hydrazone Schiff-base tetradentate ligand. A new hydrazone-Schiff base (HL) and its corresponding mononuclear and polynuclear dioxidomolybdenum(VI) complex were synthesized and characterized by spectroscopic methods and elemental analyses, and their thermal behavior was investigated by thermogravimetry.
