Purple IrCl3(CCl2)(PPh3)2 results from reaction between IrHCl2(PPh3)3 and Hg(CCl3)2.X-ray crystal structure determination reveals an octahedral complex with trans-phosphine ligands and a short Ir-C distance to the CCl2 ligand of 1.872(7) Angstroem, compatible with an iridium-carbon double bond.Chloride is easily displaced from the dichlorocarbene ligand and the products which have been derived include IrCl3(CO)(PPh3)2, IrCl3(CS)(PPh3)2, IrCl3(CNMe)(PPh3)2, IrCl3(CClNMe2)(PPh3)2, and .
