Abstract

The title compound, [IrCl(C₁₂H₈NO)₂{(CH₃)₂SO}]·H₃CCN or [IrCl(fppy)₂(DMSO)]·H₃CCN [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.

Keywords: crystal structure; iridium; phenylpyridine derivative.
