Crystal structure of chlorido(dimethyl sulfoxide-κS) bis[4-(pyridin-2-yl)benzaldehyde-κ³C²,N]- iridium(III) acetonitrile monosolvate.

The title compound, [IrCl(C12H8NO)2{(CH3)2SO}]ºH3CCN or [IrCl(fppy)2(DMSO)] ºH3CCN [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 octahedral coordination sphere. The complex crystallizes from 1:1 DMSO--acetonitrile as an acetonitrile solvate. In the crystal, weak C-- H ... O and C--H ... N hydrogen-bonding interactions between adjacent complexes and between the acetonitrile solvent and the complex consolidate the packing. [ABSTRACT FROM AUTHOR]
