31 P N.m.r. data for complexes of the types mer-[RhCl3L3], mer-[IrX3L3], and [IrCl2XL3](L = tertiary phosphine; X = Cl, Br, or I), are reported. For the complexes mer-[MCl3L3](M = Rh or Ir), there is a linear correlation between the 31P chemical shifts of the free tertiary phosphine and the change in chemical shift on co-ordination. The effects of changing the halogen, X, on the 31P chemical shifts
