Crystals of the title compound, fac , cis ‐[ReBr(C 21 H 21 P) 2 (CO) 3 ], were obtained by recrystallization of a sample from CHCl 3 layered with hexane. The geometry about the d 6 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.
