Minor modification—large effect: Replacement of Et 3 P by n Bu 3 P in otherwise homologous complexes of the type 1 can dramatically change the solid‐state NMR properties. The reason is that–although both compounds show 31 PA 2 spin systems in solution–only in one case are the 31 P nuclei also magnetically equivalent in the solid state. Therefore a reliable interpretation of the high‐resolution solid‐state 31 P NMR spectra must take into consideration the orientation‐dependent interactions within the 31 P spin pair.
