Abstract

The syntheses, characterization, and interconversions of (Et₃P)₂Ir(C₂H₄)₂Cl (1) and (Et₃P)₂Ir-(C₂H₄)(Cl) (2) as well as the X-ray crystal structure of 1 are reported. In solution complex 1 has a stereochemically rigid trigonal-bipyramidal structure with nonrotating ethylene ligands. Formation of complex 1 from complex 2 and ethylene is thermodynamically favorable; ΔG₂₉₈ = -2.12 ± 0.03 kcal/mol.
