Crystal structure of hexa­sodium tetra­serinolium paratungstate B deca­hydrate, [Na(6){(CH(2)OH)(2)CHNH(3)}(4)][W(12)O(40)(OH)(2)]·10H(2)O

The title polyoxometalate-based organic–inorganic hybrid compound, [Na(6)(C(3)H(10)NO(2))(4)][W(12)O(40)(OH)(2)]·10H(2)O, consists of a di-μ (3)-hydroxido-tetra-μ (3)-oxido-octa­deca-μ-oxido-octa­deca­oxidododeca­tungstate (para­do­deca­tungstate B) anion, [W(12)O(40)(OH)(2)](10–), and six sodium cations coordinated by the oxygen ions of the polyanions, serinol ligands protonated at the N atom, and water mol­ecules. The centrosymmetric paratungstate B anion shows characteristic features in terms of bond lengths and angles. The three-dimensional framework structure is established by bonding of the sodium cations with oxygen ions of the paratungstate B anions and a network consisting of N—H⋯O and O—H⋯O hydrogen bonds of medium strength between the protonated serinol cations, water mol­ecules and the paratungstate B anions. The title compound was also characterized by means of elemental analysis, IR spectroscopy and thermogravimetric analysis.
