The reaction of cis-Me₂Os(CO)₄ with HBF₄·Et₂O affords the complex cis- (OC)₄Os(FBF₃)CH₃ (2). The coordinated tetrafluoroborate of 2 is easily substituted by H₂O, [Re(CO)₅]⁻, [Re(CO)₄(CN)CH₃]⁻ (from Re(CO)₅CH₃ and NaN(SiMe₃)₂), SCN⁻ and PPhMe₂ to give neutral or cationic complexes 4-6, 8, 9, respectively. The structure of cis-H₃C(OC)₄Os- Re(CO)₅ has been determined by X-ray diffraction.
