Synthesis, Spectroscopy, and Biological Activity of Heterobimetallic Complexes Containing Sn(IV) and Pd(II) with 4-(Hydroxymethyl)piperidine-1-carbodithioic Acid

摘要

4-(Hydroxymethyl)piperidine-1-carbodithioic acid has been synthesized by reacting 4-pipe-ridinemethanol with carbon disulfide at room temperature. The synthesized ligand was treated with organo-tin(IV) chlorides to yield organotin complexes. These complexes by further treatment with palladium chloride afford heterobimetallic complexes containing Sn(IV) and Pd(II). The synthesized complexes along with ligand has been characterized by elemental analysis, FTIR, NMR (~1H, ~(13)G) spectroscopy. The IR data confirmed the complexation through the sulfur and oxygen donor sites of the ligand. NMR data revealed the tetrahedral geometry in the solution. Biological activity was checked against selected bacterial and fungal strains. All complexes along with the ligand were found to be biologically active with few exceptions.
