Crystal structure of abcde-pentacarbonyl-f-µ-fluoro-ghijk-pentafluoro-rhenium(I)rhenium(V)

Abstract

Crystals of the title compound are orange, orthorhombic, and have space group Pbca, a= 22.34(3), b= 15.51(1), and c= 13.67(1)Å. The structure has been refined by least-squares methods to R 0.061 for 1 969 reflections measured by diffractometer. The atomic arrangement is consistent with a covalent fluorine-bridged formulation comprising two almost identical [Re(CO)₅F]·ReF₅ molecules in the asymmetric unit. Both rhenium atoms have approximately octahedral co-ordination and are linked by a bent fluorine bridge.
