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

Abstract

In the title compound, [FeIr(C5H5)(C20H14N3) Cl3]·2CH3CN, the central IrIII atom is sixfold coordinated by three chloride ligands and three terpyridine N atoms in a slightly distorted octahedral fashion. The terpyridine ligand is functionalized at the 40 -position with a ferrocenyl group, the latter being in an eclipsed conformation. In the crystal, molecules are stacked in rows parallel to [001], with the acetonitrile solvent molecules situated between the rows. An extensive network of intra- and intermolecular C - H?Cl interactions is present, stabilizing the three-dimensional structure.
