Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.002 Å; R factor = 0.026; wR factor = 0.074; data-to-parameter ratio = 20.8.In the title compound, [Cr(C 18 H 12 F 3 P) 2 (CO) 4 ], the Cr atom is octahedrally coordinated by four carbonyl ligands and the two tertiary phosphanes that are trans to each other. The Cr atom and two carbonyl groups are on a twofold axis. The benzene rings attached to the phosphorus atom make dihedral angles of 80.32 (5), 52.91 (5) and 83.80 (5) with each other. In the crystal, C-HÁ Á ÁO and C-HÁ Á ÁF intermolecular interactions form an infinite three-dimensional network. Related literature

In the title compound, [Cr(C18H12F3P)2(CO)4], the Cr atom is octahedrally coordinated by four carbonyl ligands and the two tertiary phosphanes, which are trans to each other. The three benzene rings in one phosphane ligand make dihedral angles of 53.50 (9), 75.51 (10) and 80.63 (10)° with each other, while in the other ligand these angles are 51.92 (10), 78.56 (11) and 86.80 (10)°. C—H⋯O and C—H⋯F interactions link the molecules into a three-dimensional network. Each of the F atoms is disordered over two positions with refined occupancies of 0.944 (3):0.056 (3), 0.702 (4):0.298 (4), 0.829 (4):0.171 (4), 0.567 (4):0.433 (4), 0.545 (4):0.455 (4) and 0.920 (4):0.080 (4).
