Abstract

A new series of bromodioxomolybdenum(VI) complexes, MoO2B (S2 CNR2 )(OPPh3 ) (NR2 = NEt2 , N(i - Pr)2, NCH2(CH 2 3CH2) and MoO2Br(S 2COR)(OPPh3 ) (R = Et, n-Pr, i -Pr) were prepared by the reaction of dibr omodioxobis(triphenylphosphineoxide)molybdenum(VI ) with sodium/potassium salts of the corresponding dithiocarbamates or dithiocarbonates in 1 : 1 molar ratio in dichloromethane. These newly synthesized complexes were characterized on the basis of elements analysis and spectral (IR and 1H NMR) studies. The crystal structure of 2,5-dimethylpyridium bromide is also described. [CMeCHCHCMeCHNH]Br crystallizes as monoclinic in the space group P21/ c with cell parameters a = 8.6591(9), b = 13.25 (1), c = 7.258(1) Å, b = 101.94(1)º, V = 814.9(2) Å3, Z = 4, R = 0.0393, Rw = 0.0885.
