In the title mononuclear coordination complex, [CuFe(C(5)H(5))(C(9)H(5)F(3)O(2))(C(18)H(15)P)(2)], the Cu(I) ion is coordinated by the chelating β-diketonate 1-ferrocenyl-4,4,4-trifluoro-butane-1,3-dione ligand through two O atoms and the two datively bonded triphenyl-phosphane ligands resulting in a distorted tetra-hedral coordination sphere. The Cu(I) ion, together with its chelating butane-1,3-dione group, is mutually coplanar [greatest displacement of an atom from this plane = 0.037 (1) Å], and the Cu(I) ion lies slightly above [0.013 (1) Å] the plane. The overall geometry, including the bond distances and angles within the complex, corresponds to those of other reported copper(I) β-diketon-ates featuring organic groups at the β-diketonate ligand.
