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

The title compound, CHBrNO, crystallizes with two similar mol-ecules in the asymmetric unit. The extended structure features dimers linked by pairs of N-H⋯O and C-H⋯O hydrogen bonds. The HNCNO moiety of the title compound shows delocalization over the N-C-N part, as evidenced by the similar C-N bond distances.
