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 elementalsulfur 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
