Abstract

Reactions of dichlorodioxobis(triphenylphosphine oxide)molybdenum(VI) complexes with ammonium/sodium salts of O; O-dialkyl(alkylene) and diphenyl dithiophosphoric acids in 1:l molar ratio in dichloromethane solution yield dioxomolybdenum complexes of the types. MOO,Cl[S2P(OR)(2)] . OPPh3 (R=Me, Et, i-Pr, Ph) and MoOiCl[S(2)POGO] . OPPh3. (G=-CH2CMe2CH2O-, -OCMe2)CMe2O-). These newly synthesized compounds were characterized by IR, UV-visible and H-1 NMR spectroscopy and elemental analysis. The molecular structure of MoO2Cl2(OSMe2)(2) was determined by single-crystal X-ray diffraction. MOO)Ch(OSMe2)(2) crystallizes as orthorhombic in the space group Pbca with cell parameters a = 13.7235(3) Angstrom, b = 12.2429(2) Angstrom, c = 14.3356(3) Angstrom, V = 2408.60(8) Angstrom(-3), Z = 8, R = 0.0221, R-w = 0.0519. There are two cis oxo ligands, two cis dimethylsulphoxide moieties and two tracts chlorine atoms in a distorted octahedral environment around molybdenum.
