Abstract: In the title compound, [ReBr(C₁₆H₁₂Cl₂F₂N₂)(CO)₃], the Re atom is in a slightly distorted octahedral coordination environment with the three carbonyl ligands having a fac configuration. The diimine ligand is equatorial and is bonded to the Re centre in an N,N'-bidentate chelating fashion, with a bite angle of 77.7 (2)°. The dihedral angle between the two benzene rings is 88.7 (6)°. In the crystal structure, there are FO [2.856 (9) Å], ClC [3.150 (8) Å] and OC [2.984 (10) Å] contacts which are shorter than the sum of the van der Waals radii for these atoms. In addition, symmetry-related molecules are linked via intermolecular C-HO, C-HBr and the FO interactions into one-dimensional chains extending along the a axis. The crystal structure is further stabilized by intermolecular - interactions [centroid-centroid distance = 3.571 (5) Å].
