Four new hexavanadate cluster-based hybrid materials [Ni(3-atrz)(2)V2O6]center dot 2H(2)O (1) and [M-3(4-atrz)(6)V6O18]center dot 4H(2)O [atrz = amino-1,2,4-triazole; M = Ni (2), Co (3) and Zn (4)] have been synthesized under hydrothermal conditions by the reaction of transition metal salts, amino-triazole ligands and sodium metavanadate. Single crystal X-ray diffraction analyses reveal that compound 1 shows a one-dimensional (1D) chain formed by the alternative arrangement of linear trinuclear complexes [Ni-3(3-atrz)(6)](6+) and hexanuclear [V6O18](6-) clusters. Compounds 2-4 are isostructural three-dimensional (3D) frameworks, which are constructed from the linear trinuclear transition metal complexes and 2D inorganic layers derived from transition metal ions and hexanuclear [V6O18](6-) clusters. The distinct amino positions in the two types of triazole ligands play the key role in determining the final dimensionality and structures of the title compounds. The thermal stability, photocatalytic activity and magnetic properties of 1-4 have been investigated.
