A new decavanadate [Zn(en)2]3[V10O28]·5H2O (1), (en = ethylenediamine) has been hydrothermally synthesized and characterized by elemental analysis, infrared spectroscopy, thermogravimetry, and single-crystal X-ray diffraction. It is a structural feature of compound 1 that each [V10O28]6− cluster provides four bridging oxygen atoms of two pairs of opposite [VO6] octahedra to graft four [Zn(en)2]2+ complexes, observed for the first time for the [V10O28]6− cluster. The resulting array represents the second example of a chain based on these decavanadates linked by transition metal complexes.
