Influence of ancillary ligands on the formation and functionality of oxovanadium(V) metallosupramolecular assemblies: advanced computational and catalytic analyses.

A coordination-driven self-assembly approach offers an opportunity for designing metallosupramolecular architectures with tailored properties. Applying this strategy, we present the synthesis and detailed characterization of tetranuclear and polynuclear vanadium(V) compounds with an aroylhydrazone ligand. These assemblies were obtained using the 3-methoxy-2-hydroxybenzaldehyde isonicotinoyl hydrazone ligand (HVIH) and NHVO in the presence of primary aliphatic alcohols with increasing carbon chain length (from one to five carbon atoms).

High-valent oxovanadium metallosupramolecular species as catalysts for the oxidation of benzyl alcohol derivatives.

Coordination-driven synthesis has been successfully utilized to prepare vanadium-based metallosupramolecular species. By systematically varying synthesis methods and reaction conditions, two series of isostructural oxovanadium(v) coordination polymers [VO(SIH)(OR)] (where SIH represents salicylaldehyde isonicotinoylhydrazonate, and R corresponds to CH (1β·0.25CHOH), CH (2α and 2β·0.

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.
