A novel nanomolecular organic–inorganic hybrid compound: Na2[NH(CH2CH2OH)3]4{Mo36O112(OH2)14[OHCH2CH2NH(CH2CH2OH)2]2}·nH2O (n≈72) exhibiting a supramolecular one-dimensional chainlike structure

A novel nanomolecular organic–inorganic hybrid compound, Na2[NH(CH2CH2OH)3]4{Mo36O112(OH2)14 [OHCH2CH2NH(CH2CH2OH)2]2}·nH2O (n≈72) (1), was synthesized in aqueous acidic medium with a high yield (85%) and characterized by single crystal X-ray crystallography, IR spectroscopy, 1H NMR, XRD and TG analysis. Compound 1 exhibits a supramolecular one-dimensional chainlike structure which consists of nanosized {[Mo36O112(H2O)14(HOC2H4)2NHC2H4OH]2}6− anions ({Mo36(TEAH+)2} for short) and cage-like dimers of TEAH+ cations (TEAH+=protonated triethanolamine). In the {Mo36(TEAH+)2} anion, two TEAH+ cations connect to one ring-like {[Mo36O112(H2O)16]8− ({Mo36} for short) anion by covalent bonds via replacing two water ligands by the alkoxy ligands. The {Mo36(TEAH+)2} unit could be considered as nanosized chelating ligand with [2N, 4O] donor sets. Crystal Data: triclinic, P-1, a=16.019(9) Å, b=17.372(4) Å, c=18.287(2) Å, α=101.410(0)°, β=95.904(0)°, γ=116.332(0)°, Z=1.

A novel organic–inorganic hybrid material based on macroisopolyanion {Mo36} 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 {Mo36(TEAH+)2} unit could be considered as nanosized chelating ligand with [2N, 4O] donor sets.Figure optionsDownload as PowerPoint slide
