The degenerate rearrangement of P73- has been studied by means of the MINDO/3 method. The calculated enthalpy of activation (⊿H≠ = 59.12 kJ/mol) is in good agreement with results from 31P NMR studies at different temperatures. The bond switching process starts with a bond rupture leading to a transition state with C2v symmetry. Possible rearrangements in P6S2-and P6CH2-are discussed.
