(eta6-2-Bromo-1,1'-biphenyl)-tricarbonylchromium.

The title compound, [Cr(C(12)H(9)Br)(CO)(3)], crystallizes in the triclinic space group P-1 with close Br.Br separations. These contacts, along with several other factors, influence the (Ph)C-C(o-BrC(6)H(4)) dihedral angle of 58.82 (6) degrees. The typical piano-stool coordination about the Cr atom is in excellent agreement with the results of density functional theory calculations.
