A novel nanomolecular organic-inorganic hybrid compound, Na-2[NH(CH2CH2OH)(3)](4){Mo36O112(OH2)(14) [OHCH2CH2NH(CH2CH2OH)(2)](2)}center dot nH(2)O (n approximate to 72) (1), was synthesized in aqueous acidic medium with a high yield (85%) and characterized by single crystal X-ray crystallography, IR spectroscopy, H-1 NMR, XRD and TG analysis. Compound 1 exhibits a supramolecular one-dimensional chainlike structure which consists of nanosized {[Mo36O112(H2O)(14)(HOC2H4)(2)NHC2H4OH](2)}(6-) anions ({Mo-36(TEAH(+))(2)} for short) and cage-like dimers of TEAH(+) cations (TEAH(+) = protonated triethanolamine). In the {Mo-36(TEAH(+))(2)} anion, two TEAH(+) cations connect to one ring-like {[Mo36O112(H2O)(16)](8-) ({Mo-36} for short) anion by covalent bonds via replacing two water ligands by the alkoxy ligands. The {Mo-36(TEAH(+))(2)} unit could be considered as nanosized chelating ligand with [2N, 40] donor sets. Crystal Data: triclinic, P-1, a = 16.019(9)angstrom, b = 17.372(4)angstrom, c = 18.287(2)angstrom, alpha = 101.410(0)degrees, beta = 95.904(0)degrees, y = 116.332(0)degrees, Z = 1.
