Description
Summary:The title polyoxometalate-based organic-inorganic hybrid compound, [Na (C H NO ) ][W O (OH) ]·10H O, consists of a di- -hydroxido-tetra- -oxido-octa-deca- -oxido-octa-deca-oxidododeca-tungstate (para-do-deca-tungstate B) anion, [W O (OH) ] , 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.
