Chlorido(ethylenediamine-²N)(⁵-pentamethylcyclopentadienyl)iridium(III) trifluoromethanesulfonate

M. Scharwitz, T. van Almsick and W. S. Sheldrick

Abstract: The title compound, [Ir(⁵-C₅Me₅)Cl(en-²N)](CF₃SO₃) (en is ethylenediamine) or [Ir(C₁₀H₁₅)Cl(C₂H₈N₂)](CF₃SO₃), contains a half-sandwich (⁵-C₅Me₅)Ir^III fragment coordinated in a bidentate manner by the N atoms of an en ligand. N-HO hydrogen bonds between the en amino groups and O atoms of the trifluoromethanesulfonate anions generate polymeric chains. The cation and anion both have C_s symmetry. The C atoms of the en ligand are disordered about a mirror plane. The crystal structure involves N-HO, C-HO and N-HCl hydrogen bonds.
