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).
在标题化合物[Cr(C₁₈H₁₂F₃P)₂(CO)₄]中，Cr原子由四个羰基配体和两个叔膦以八面体方式配位，这两个叔膦彼此呈反式。一个膦配体中的三个苯环相互间的二面角分别为53.50 (9)°、75.51 (10)°和80.63 (10)°，而在另一个配体中这些角度分别为51.92 (10)°、78.56 (11)°和86.80 (10)°。C—H⋯O和C—H⋯F相互作用将分子连接成三维网络。每个F原子在两个位置上无序分布，精修占有率分别为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)和0.920 (4):0.080 (4)。
