Abstract

Oxidation of a blue ethanolic mixture containing Co(BF₄) ₂·6H₂O and PClPh₂ by tetramethylthiuram disulfide afforded a red-colored complex having a cis-[Co^III(Me ₂dtc)₂(P)₂] environment (Me₂dtc ^- = N,N-dimethyldithiocarbamate), although the yield was relatively low. Single-crystal X-ray crystallography revealed that the product was [Co(Me₂dtc)₂{(Ph₂PO)₂BF ₂}] (1), where bis(diphenylphosphinito)difluoroborate was probably formed by hydrolysis of PClPh₂ followed by reaction with BF ₄^- in ethanol. The same complex was also prepared by hydrolysis of cis-[Co(Me₂dtc)₂(PHPh₂) ₂]BF₄ in a mixture of acetonitrile, methanol and water. The molecular structure and spectroscopic properties of complex 1 were compared with those of the corresponding Ph₂POMe complex, cis-[Co(Me ₂dtc)₂(Ph₂POMe)₂]BF₄.
