摘要: The synthesis and spectroscopic characterization of three chalcogenophosphoryl ligands derived from pyridine is reported. The was based on the oxidation C5H3N(PPh2)(2) by elemental sulfur selenium, hydrogen peroxide. As a part of our study coordination chemistry ligands, three new Sn(IV) complex cations general formula {[Ph2P(E)-C5H3N-P(E)Ph-2]SnCl3}(+) (E = O, S, Se) were also synthesized. All compounds characterized by P-31 NMR and X-ray crystallography. organic are tridentate, with both chalcogens nitrogen involved in chelation. cations show an approximate octahedral core geometry paired with either SnCl5- or SnCl5(OH2)(-) anions.
