ambidentate nature of the P–N function: amide-coordination in the Mg-complex (S,S)-7 and P-chelation of the softer Ir(I) centres in complexes rac-9 and rac-10. Furthermore, the crystal structures show flexible, symmetry lowering seven-membered P-chelate rings in the Ir complexes and a surprising amount of deformation within the ANDEN backbone. The simulation of this deformation by DFT and SCF calculations
