Synthesis, spectrothermal and structural characterization of saccharinatobis(tris-hydroxymethylaminomethane)zinc(II)saccharinate complex, [Zn(sac)(tham)(2)](sac)
Özet
A novel Zn-II complex of the saccharinate ligand (sac) with tris-hydroxymethylaminomethane (tham) was synthesized and characterized by elemental analysis, FT-IR spectroscopy, simultaneous TG and DTA techniques, and X-ray diffraction. The complex, [Zn(sac)(tham)(2)](sac), crystallizes in monoclinic system with space group P2(1)/c [a = 7.55954(3) angstrom, b = 13.0532(6) angstrom, c = 27.7777(10) angstrom, beta = 100.539(3)degrees, Z = 4]. The Zn-II ion has a distorted octahedral coordination. The tham ligand has chemically different functions in the structure, acting as both bidentate and tridentate ligands. There are also sac moieties to act as N-bonded ligand and as a counter anion. The molecular packing of the complex is provided by moderate hydrogen bonds as well as pi center dot center dot center dot pi interactions between the sac moieties. The IR spectra and the thermal decomposition of the complex are also discussed.
