Abstract

The complex [IrCl~3~(CO)(1)](4,1=2,11‐bis (diphenylphosphinomethyl)benzo[c]phenanthrene) has been prepared by CuCl~2~‐oxidation of IrCl(CO)(1). 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).
