The preparation and properties of a series of rhenium compounds of the general formula (η-C5H5)Re(CO)2XY in which X or Y or both is a silyl, germyl, or stannyl ligand are reported.The silyl hydrides cis-(η-C5H5)Re(CO)2(SiR3)H (R=Ph, CH2Ph) and cis-(η-C5H5)Re(CO)2(SiPh2H)H were obtained by ultraviolet irradiation of (η-C5H5)Re(CO)3 and the appropriate silane.The hydrides trans-(η-C5H5)Re(CO)2XH (X=SiPh3, GeCl3, GeBr3, SnCl3) were obtained by protonation of the corresponding anions.These new anions (1-) also reacted with other electrophiles to yield compounds of the type trans-(η-C5H5)Re(CO)2XY (Y=Me, halogen, SnR3).The reaction of (η-C5H5)Re(CO)3 with Cl3GeH or Ph3SnH yielded only the compounds trans-(η-C5H5)Re(CO)2(GeCl3)2 and trans-(η-C5H5)Re(CO)2(SnPh3)2 respectively.Infrared and 1H nmr spectra are reported for all compounds, and ν(Re-H) values for the hydrides have been obtained from Raman spectra.
