Özet
A new Hg(II) complex 1 was synthesised from a 3-methoxysalicylaldehyde-4-methylthiosemicarbazone ligand (H2L) via one-pot reaction and characterized by FT-IR, 1H NMR, mass spectroscopy, elemental analysis, and single-crystal X-ray diffraction analysis. The complex 1 adopts a distorted seesaw [HgN2S2] coordination geometry. Coordination to Hg(II) promotes a thione–thiol tautomeric conversion in the ligand (H2L), forming a deprotonated thiolate donor. Structural analysis, combined with Hirshfeld surface and enrichment ratio evaluations, unveiled that O⋯H and C⋯C contacts play dominant roles in supramolecular stabilization. Density Functional Theory (DFT) analysis suggests a substantial amount of charge transfer from H2L to Hg(II). These results highlight how the interplay between coordination-induced tautomerism and noncovalent forces governs the molecular organization of the Hg(II) complex …
