Crystal structure of tri-chlorido-(4'-ferrocenyl-2,2':6',2''-terpyridine-κ(3) N,N',N'')iridium(III) aceto-nitrile disolvate.

In the title compound, [FeIr(C5H5)(C20H14N3)Cl3]·2CH3CN, the central Ir(III) atom is sixfold coordinated by three chloride ligands and three terpyridine N atoms in a slightly distorted octa-hedral fashion. The terpyridine ligand is functionalized at the 4'-position with a ferrocenyl group, the latter being in an eclipsed conformation. In the crystal, mol-ecules are stacked in rows parallel to [001], with the aceto-nitrile solvent mol-ecules situated between the rows. An extensive network of intra- and inter-molecular C-H⋯Cl inter-actions is present, stabilizing the three-dimensional structure.
