A novel nanomolecular organic-inorganic hybrid compound, Na{sub 2}[NH(CH{sub 2}CH{sub 2}OH){sub 3}]{sub 4}{l_brace}Mo{sub 36}O{sub 112}(OH{sub 2}){sub 14} [OHCH{sub 2}CH{sub 2}NH(CH{sub 2}CH{sub 2}OH){sub 2}]{sub 2}{r_brace}.nH{sub 2}O (n{approx}72) (1), was synthesized in aqueous acidic medium with a high yield (85%) and characterized by single crystal X-ray crystallography, IR spectroscopy, {sup 1}H NMR, XRD and TG analysis. Compound 1 exhibits a supramolecular one-dimensional chainlike structure which consists of nanosized {l_brace}[Mo{sub 36}O{sub 112}(H{sub 2}O){sub 14}(HOC{sub 2}H{sub 4}){sub 2}NHC{sub 2}H{sub 4}OH]{sub 2}{r_brace}{sup 6-} anions ({l_brace}Mo{sub 36}(TEAH{sup +}){sub 2}{r_brace} for short) and cage-like dimers of TEAH{sup +} cations (TEAH{sup +}=protonated triethanolamine). In the {l_brace}Mo{sub 36}(TEAH{sup +}){sub 2}{r_brace} anion, two TEAH{sup +} cations connect to one ring-like {l_brace}[Mo{sub 36}O{sub 112}(H{sub 2}O){sub 16}]{sup 8-} ({l_brace}Mo{sub 36}{r_brace} for short) anion by covalent bonds via replacing two water ligands by the alkoxy ligands. The {l_brace}Mo{sub 36}(TEAH{sup +}){sub 2}{r_brace} unit could be considered as nanosized chelating ligand with [2N, 4O] donor sets. Crystal Data: triclinic, P-1, a=16.019(9) A, b=17.372(4) A, c=18.287(2) A, {alpha}=101.410(0){sup o}, {beta}=95.904(0){sup o}, {gamma}=116.332(0){sup o}, Z=1. - Graphical abstract: A novel organic-inorganic hybrid material based on macroisopolyanion {l_brace}Mo{sub 36}{r_brace} has been synthesized and characterized by X-ray single-crystal crystallography, XRD, IR spectroscopy, and TG analysis. The material exhibits a supramolecular one-dimensional chainlike structure. The {l_brace}Mo{sub 36}(TEAH{sup +}){sub 2}{r_brace} unit could be considered as nanosized chelating ligand with [2N, 4O] donor sets.
