摘要:
The title compound, [IrCl(C3H5O)(C5H4NO){(C3H7)(3) P}(2)], is a mononuclear complex of a chelated 2(1H)-pyridone anion, exhibiting slightly distorted octahedral geometry. The monohapto carbon-bound propionyl ligand and the O atom of the dihapto pyridonato ligand are mutually trans, and the phosphine ligands tilt away from the propionyl ligand towards the O atom of the heterocyclic ligand. The Ir-O bond length is unusually long for a complex of 2(1H)-pyridone, a circumstance attributed to the strong trans influence of the acyl ligand.
