Synthesis, characterization and X-ray crystal structure of a mononuclear ampyrone based zinc complex

A novel mononuclear zinc complex derived from a pyrazole-based ligand was studied. The structure of the complex was explored using C, H, N, FT-IR, NMR, and UV/Vis studies, thermogravimetric analysis, and single-crystal X-ray crystallography. The single XRD study shows the coordination of the zinc ion to the alkoxide oxygen atom, two chloride ions, and one additional oxygen atom from the ethanol molecule in the complex. The intermolecular interactions in the complex were investigated using Hirshfeld surface analysis and revealed that the H...H is the most important interaction, accounting for 45.9% of the overall crystal packing contribution of the complex.
