Two novel organic–inorganic hybrid vanadoantimonate compounds, [Zn<sub>2sub>(dien)<sub>3sub>][{Zn(dien)}<sub>2sub>V<sub>16sub>Sb<sub>4sub>O<sub>42sub>(H<sub>2sub>O)]¡¤4H<sub>2sub>O (1) and [Zn(dien)<sub>2sub>]<sub>2sub> [{Zn(dien)}<sub>2sub>(V<sub>14sub>Sb<sub>8sub>O<sub>42sub>)<sub>2sub>(H<sub>2sub>O)]¡¤4H<sub>2sub>O (2) (dien = Diethylenetriamine), have been synthesized hydrothermally at different pH value, and structurally characterized by elemental analyses, FT-IR, XPS, TGA and single crystal X-ray diffraction analysis. Compound 1 is composed of the rare [V<sub>16sub>Sb<sub>4sub>O<sub>42sub>]8− cluster covalently linked by two [Zn(dien)]2+ coordination cations to yield a novel one-dimensional linear chain. Compound 2 exhibits a one-dimensional zigzag chain constructed from the [V<sub>14sub>Sb<sub>8sub>O<sub>42sub>]4− cluster and [Zn(dien)]2+ coordination polymer. The two examples represent the first one-dimensional assemblies based on vanadoantimonate cluster and the metal–organic complex moieties.
