The cluster aqua complexes [Mo3(MCl)Q4(H2O)9]3+ (M = Pd or Ni) in hydrochloric acid solutions induce isomerization of the hydrophosphoryl compounds (HO)2P(O)H, (HO)P(O)H2, PhP(O)(OH)H, and Ph2P(O)H into the hydroxo tautomers P(OH)3, HP(OH)2, PhP(OH)2, and Ph2P(OH), which are stabilized by coordination of the phosphorus atom to the Pd or Ni atoms. The reactions were studied by 31P NMR and UV-Vis spectroscopy. The kinetics of the reactions of phosphorous acid with [Mo3(PdCl)Q4(H2O)9]3+ was…

Synthesis, structure and reactivity of cuboidal-type cluster aqua complexes with W3PdS44+ core
The reaction of PdCl2 with [W3S4(H2O)9]4+ in the presence of hypophosphorous acid in 2 M HCl gives cuboidal cluster [W3(PdCl)S4(H2O)9]3+ (1) which undergoes condensation and crystallises from Hpts
Kinetic, DFT and TD-DFT studies on the mechanism of stabilization of pyramidal H3PO3 at the [Mo3M'S4(H2O)10]4+ clusters (M' = Pd, Ni).
TLDR
DFT calculations indicate that tautomerization of H(3)PO(3), both processes being less favored at the Ni cluster than at its Pd analogue, involves essentially ligand-to-metal charge-transfer (LMCT) transitions.

Combined kinetic and DFT studies on the stabilization of the pyramidal form of H3PO2 at the heterometal site of [Mo3M'S4(H2O)10]4+ clusters (M' = Pd, Ni).
TLDR
The major finding is that the role of the additional H(3)PO(2) molecule in the second step consists in catalysing a hydrogen shift from phosphorus to oxygen in O-coordinated H( 3) PO(2), which is made possible by its capability of accepting a proton from P-H to form H(4)PO (2)(+) and then transfer it to the oxygen.

Unprecedented solvent-assisted reactivity of Hydrido W3CuS4 cubane clusters: the non-innocent behaviour of the cluster-core unit.
TLDR
A mechanism for the substitution reaction is proposed in which attack at the copper centre by acetonitrile or water causes disruption of the cubane-type core and this kind of process is unprecedented in the chemistry of M(3)M'Q(4) (M=Mo, W; Q=S, Se) clusters.

TLDR

TLDR
The kinetics of conversion of an edge-linked double cube to the corresponding single cube has been studied for the first time and can be explained by substitution at nonidentical H(2)O's on each Mo or by the presence of mixed-valent Mo(III)(2)Mo(IV) forms which are sufficiently long-lived to give a kinetic discrimination.
