Transition-metal carbonyl derivatives of the germanes. Part IV. Germylpentacarbonylrhenium

Abstract

Physical and spectroscopic properties of germylpentacarbonylrhenium, GeH₃Re(CO)₅, (I) prepared through reaction of germyl bromide with NaRe(CO)₅, are reported and compared with those of the manganese analogue and other related complexes. A further product, isolated in very low yield during the formation of (I), is tentatively identified as bis(pentacarbonylrhenium)germane. GeH₂[Re(CO)₅]₂(II). Ions arising from transfer of hydrogen from Ge to Re are of unusually high abundance in the mass spectrum of (I).
