碩士 === 中原大學 === 化學研究所 === 93 === Complexes (C6H5)3MSe2P(OR)2 (M＝Ge, Pb；R＝iPr, Et, nPr) were prepared from the reaction of (C6H5)3MCl and NH4Se2P(OR)2 in a molar ratio of 1:1 in diethyl ether at 0 °C. The complexes were characterized by elemental analysis, 1H, 31P, 77Se NMR, positive FAB mass and X-ray. The X-ray structure consists of three phenyl rings connected to metal atom and a selenium atom from diselenophosphate ligand is also coordinated to metal atom. The other selenium atom of diselenophosphate ligand is dangling. The coordination geometry around the metal atom is distorted tetrahedral. Compounds Pb[Se2P(OR)]2 (R＝iPr, Et, nPr,) were prepared from the reaction of Pb(CH3COO)2•3H2O and NH4Se2P(OR)2 in a molar ratio of 1:2 in methanol at room temperature. The complexes were characterized by elemental analysis, 1H, 31P, 77Se NMR, positive FAB mass and X-ray.
