摘要

The solvothermal reaction of Hbta (Hbta = benzotriazole) and Ni(NO3)(2)center dot 6H(2)O yielded a blue block crystal, [Ni-9(bta)(12)(NO3)(6)(DMA)(6)]center dot 3DMA (1), (DMA = N,N-dimethylacetamide), which has been characterized by various measurements including elemental analysis, thermogravimetric (TG) analysis, infrared (IR) spectrum, powder X-ray diffraction (PXRD), and X-ray single-crystal diffraction. In compound 1, three crystallographic independent Ni2+ ions are connected by two types of Hbta ligands to generate a centrosymmetric nine-nuclear (NW cluster, which could further form a 3D supramolecular network through intra-and intermolecular hydrogen bonds. The TG curve of 1 exhibits a weight loss between 25 and 330 degrees C, being in accordance with the release of DMA. Furthermore, the variable-temperature magnetic susceptibility of 1 has studied, and the results indicate that antiferromagnetic interactions exist among Ni2+ ions.
