Summary: | The affinity of [β-Mo
O
]
toward different proton sources has been studied in various conditions. The proposed sites for proton coordination were highlighted with single crystal X-ray diffraction (SCXRD) analysis of (Bu
N)
[β-{Ag(py-NH
)Mo
O
]}] (
) and from analysis of reported structures. Structural rearrangement of [β-Mo
O
]
as a direct response to protonation was studied in solution with
Mo NMR and HPLC-ICP-AES techniques. A new type of proton transfer reaction between (Bu
N)
[β-Mo
O
] and (Bu
N)
H
[V
O
] in DMSO results in both polyoxometalates transformation into [V
Mo
O
]
, which was confirmed by the
Mo,
V NMR and HPLC-ICP-AES techniques. The same type of reaction with [H
SiW
O
] in DMSO leads to metal redistribution with formation of [W
Mo
O
]
