Abstract:
In the title compound, [Ir(C(18)H(15)P)(2)(CO)(3)]PF(6)·CH(3)OH, the Ir(I) atom is coordinated by two triphenyl-phosphine ligands in axial sites and three carbonyl ligands in the equatorial plane of a fairly regular trigonal bipyramid: the equatorial C-Ir-C angles range from 115.45 (9) to 126.42 (10)°. The small deviations from the ideal tetra-hedral geometry around the P atoms are illustrated by C-P-C angles ranging from 104.08 (9) to 106.46 (9)°. In the crystal, the mol-ecules are linked by weak C-H⋯F, C-H⋯O and C-H⋯π inter-actions.
