Serendipitous preparation of fac-(acetonitrile-κN)trichlorido[(1,2,5,6-η)-cycloocta-1,5-diene]iridium(III)

Abstract

A reaction between [(COD)IrCl]2 (COD is cycloocta-1,5-diene), HCl and indene failed to provide the hoped for chloridoindenyliridium dimer, but instead produced the title compound, [IrCl3(CH3CN)(C8H12)], which is an octahedral complex of iridium(III) with a chelating cycloocta-1,5-diene ligand, three chloride ligands in a fac arrangement, and one acetonitrile ligand. Attempts to devise a rational synthesis for the title compound were unsuccessful.
