摘要

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, Prⁿ, Prⁱ) or MoO₂Br(S₂COR)(OSMe₂) (R = Et, Prⁿ, Prⁱ). These newly synthesized complexes were characterized by elemental analysis and IR, UV–Vis and ¹H NMR spectroscopy. Crystals of MoO₂Br₂(OSMe₂)₂ and MoO₂Br₂(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.
