We are pleased to share that Dr. Subhadip Roy, Department of Chemistry, The ICFAI University Tripura, has co-authored a research article published in Polyhedron (Elsevier):
“Substituent-driven supramolecular assembly in Hg(II) bromide complexes with pyridine-based hydrazone ligands: crystal structures, Hirshfeld surface analysis, and DFT/QTAIM study”
This work is a collaborative effort involving researchers from institutions in Russia, Iran, Azerbaijan, Italy, Turkey, and India, including The ICFAI University Tripura. The study examines how substituent variation on pyridine-based hydrazone ligands directs the solid-state organization of Hg(II) bromide complexes.
Combining single-crystal X-ray crystallography, Hirshfeld surface analysis, and DFT/QTAIM calculations, the article shows how modest changes at the ligand periphery reshape non-covalent contacts and the resulting supramolecular architecture.
Congratulations to Dr. Subhadip Roy and all co-authors on this contribution to coordination and supramolecular chemistry.
