Abstract
The title polyoxometalate-based organic-inorganic hybrid compound, [Na6(C3H10NO2)4][W12O40(OH)2]·10H2O, consists of a di-μ 3-hydroxido-tetra-μ 3-oxido-octa-deca-μ-oxido-octa-deca-oxidododeca-tungstate (para-do-deca-tungstate B) anion, [W12O40(OH)2]10-, and six sodium cations coordinated by the oxygen ions of the polyanions, serinol ligands protonated at the N atom, and water mol-ecules. 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 mol-ecules and the paratungstate B anions. The title compound was also characterized by means of elemental analysis, IR spectroscopy and thermogravimetric analysis.
