【 摘 要 】
The asymmetric unit of the title compound, [Ir(C17H11F2N2)3]·0.5CH3(CH2)4CH3·0.5CH2Cl2, comprises one IrIII atom, three 2,6-difluoro-3-[5-(2-fluorophenyl)pyridin-2-yl]pyridin-4-yl ligands and half each of an n-hexane and a dichloromethane solvent molecule located about crystallographic inversion centres. The IrIII atom displays a distorted octahedral coordination geometry, having three C,N-chelating 2,6-difluoro-3-[5-(2-fluorophenyl)pyridin-2-yl]pyridin-4-yl ligands arranged in a meridional manner. The IrIII ion lies almost in the equatorial plane [deviation = 0.0069 (15) Å]. The average distance [2.041 (3) Å] of Ir—C bonds is slightly shorter than that [2.076 (3) Å] of Ir—N bonds. A variety of intra- and intermolecular C—H⋯F and C—H⋯π hydrogen bonds, as well as intermolecular C—F⋯π interactions, contribute to the stabilization of the molecular and crystal structures, and result in the formation of a two-dimensional network parallel to the ab plane. No interactions between n-hexane solvent molecules and the other components in the title compound are observed.
