TY - JOUR ID - 555397 AU - Ševčík, Richard - Nečas, Marek - Novosad, Josef PY - 2003 TI - The synthesis and characterization of three oxidized derivatives of bis(diphenylphosphino)pyridine and their Sn(IV) complexes JF - POLYHEDRON VL - 22 IS - 12 SP - 1585-1593 EP - 1585-1593 PB - PERGAMON-ELSEVIER SCIENCE LTD SN - 02775387 KW - COORDINATION CHEMISTRY KW - 2;6-BIS(DIPHENYLPHOSPHINO)PYRIDINE N2 - The synthesis and spectroscopic characterization of three chalcogenophosphoryl ligands derived from pyridine is reported. The synthesis was based on the oxidation of C5H3N(PPh2)(2) by elemental sulfur and selenium, and hydrogen peroxide. As a part of our study on the coordination chemistry of the ligands, three new Sn(IV) complex cations of the general formula {[Ph2P(E)-C5H3N-P(E)Ph-2]SnCl3}(+) (E = O, S, Se) were also synthesized. All compounds were characterized by P-31 NMR and X-ray crystallography. The organic ligands are tridentate, with both chalcogens and nitrogen involved in chelation. The cations show an approximate octahedral core geometry and are paired with either SnCl5- or SnCl5(OH2)(-) anions. ER -
