Trans-Tetra-carbonyl-bis-[tris-(3-fluoro-phen-yl)phosphane]chromium(0).

ABSTRACT: In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally 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 inter-actions link the mol-ecules 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).
