Metalation of N‐mesityl‐P,P‐diphenylphosphinic amide Ph2P(=O)–N(H)Mes (1) with n‐butyllithium, sodium amide and potassium hydride yields the corresponding alkali metal N‐mesityl‐P,P‐diphenylphosphoryl amides of lithium (2), sodium (3), and potassium (4). The lithium complex 2 forms a dimer with an eight‐membered (Li–O–P–N)2 ring. The sodium derivative 3 crystallizes as a dinuclear centrosymmetric complex with a central Na2O2 ring. The potassium congener 4 precipitates as a tetranuclear compound with an inner K4O4 heterocubane cage. In these complexes the phosphoryl amido ligands act as bidentate Lewis bases and form strained four‐membered M–O–P–N rings. Due to this fact, the endocyclic M–O bonds of the M2O2 rings vary within a large range.
