Abstract: Crystals of the title compound, fac,cis-[ReBr(C₂₁H₂₁P)₂(CO)₃], were obtained by recrystallization of a sample from CHCl₃ layered with hexane. The geometry about the d⁶ Re^I centre is (distorted) octahedral with the three CO ligands fac and the two tribenzylphosphine ligands cis. In accordance with the trans influence, the Re-C bond trans to Br is significantly shorter than those trans to the organophosphine ligands.
