Trans-Tricarbonylbis[diphenyl(benzoylmethyl)phosphine]iron(0)

Abstract

In the crystal structure of the title compound, trans-(Ph2PCH2COPh)2Fe(CO)3, the molecule occupies a special position: the Fe atom and one of the carbonyl groups lie on the twofold axis. The Fe atom has an almost undistorted trigonal-bipyramidal coordination environment. The trans-phosphine ligands are in axial positions, the PFeP unit being almost linear [P—Fe—P 178.86 (3)°; Fe—P 2.2113 (4) A] and orthogonal to the Fe(CO)3 plane [P—Fe—C 88.85 (6)°, 90.568 (14)°, and 90.61 (6)°].
