Crystal structure of chlorido-(dimethyl sulfoxide-κS)bis-[4-(pyridin-2-yl)benzaldehyde-κ(3)C(2),N]iridium(III) aceto-nitrile monosolvate.

The title compound, [IrCl(C(12)H(8)NO)(2){(CH(3))(2)SO}]·H(3)CCN or [IrCl(fppy)(2)(DMSO)]·H(3)CCN [where fppy is 4-(pyridin-2-yl)benzaldehyde and DMSO is dimethyl sulfoxide], is a mononuclear iridium(III) complex including two fppy ligands, a sulfur-coordinating DMSO ligand, and one terminal chloride ligand that define a distorted octa-hedral coordination sphere. The complex crystallizes from 1:1 DMSO-aceto-nitrile as an aceto-nitrile solvate. In the crystal, weak C-H⋯O and C-H⋯N hydrogen-bonding inter-actions between adjacent complexes and between the aceto-nitrile solvent and the complex consolidate the packing.
