Almost all representations of phosphates <(RO)3P=O>, trialkyl phosphine oxides (R3P=O) and related species include a double bond between phosphorus and oxygen.However, we strongly oppose the double-bond representation and maintain that it is misleading.EPR evidence for electron-loss centres are shown to be in accord with the structures (R)3(+)P-O(.), with small, negative spin density on phosphorus.Also, electron addition shows that there are no low-lying vacat 3d orbitals available for the excess electrons, which occupy a largely nonbonding ? orbital with high spin-density in the 3s orbital on phosphorus.These results cannot be reconciled with any of the concepts which lead to the P=O formulation.
