fac-Bromidotricarbonyl[2-(diisopropylphosphanyl)benzaldehyde-κ2 O,P]rhenium(I)

{Bromo-fac-tricarbonyl-[\h^2^-P,O-(2-\ diisopropylphosphinobenzaldehyde)]-rhenium(I)}is obtained from the reaction of 2-diisopropylphosphinobenzaldehydedimethylacetale and Bromentacarbonyl-Rhenium(I) in the presence of traces of water. It crystallizes with one molecule in the crystallographically independent unit of the monoclinic elemetary cell. The structure clearly shows firstly the facial coordination of the three CO ligands and the \h^2^-P,O-coordination mode of the 2-diisopropylphosphinobenzaldehyde ligand. The Re---C bond distance for the CO ligand trans to the P-atom is due to its trans influence elongated to 1.943(3) \%A. With respect to the standard deviations this is a proof that the CO-ligand is weaker bound to the Re center than the other two CO ligands.
