- Abstract
The complex [IrCl3(CO)( 1)]( 4,1=2,11-bis (diphenylphosphinomethyl)benzo[ c]phenanthrene) has been prepared by CuCl2-oxidation of [IrCl(CO)( 1)]( 2a). It is shown that the chlorine oxidation of 2a gives a mixture of products whose composition depends on the reaction conditions. The X-ray crystal structures of 2a and 4 have been determined. The small conformational differences observed for the trans-spanning ligand 1 in the two complexes are likely to be caused by the difference in Ir-P bond lengths in square planar 2a and octahedral 4 (2.310(4) and 2.411(3) Å, respectively).
