Catalytic effect of a second H3PO2 in the mechanism of stabilisation of the unstable pyramidal tautomer of H3PO2 coordinated at [Mo3S4M'] clusters (M' = Ni, Pd).
Kinetic and DFT studies indicate that the stabilization of a single pyramidal H(3)PO(2) molecule at the M' site of [Mo(3)S(4)M'] clusters requires the participation of two tetrahedral H(3)PO(2) molecules, the role of the second one being assisting tautomerization of a previously coordinated tetrahedral H(3)PO(2).
