Abstract
Reactions of dibromodioxobis(dimethylsulfoxide)molybdenum(VI) with sodium/potassium salts of N,N'-dialkyl dithiocarbamates or O-alkyl dithiocarbonates in 1:1 molar ratio in dichloromethane yield bromodioxomolybdenum(VI) complexes of the type, MoO2Br(S2CNR2)(OSMe2) (R = Et, Pr-n, Pr-i) or MoO2Br(S2COR)(OSMe2) (R = Et, Pr-n, Pr-i). These newly synthesized complexes were characterized by elemental analysis and IR, UV-Vis and H-1 NMR spectroscopy. Crystals of MoO2,Br-2(OSMe2)(2) and MoO2Br(2)(C12H8N2) • CH2Cl2 both have distorted octahedral environments around molybdenum with two cis-oxygen atoms and two trans-bromine atoms along with two cis-dimethylsulfoxide moieties in the former and 1,10-phenanthroline in the latter.
