摘　　要：采用水热合成法,通过配体5,5'-二氰基-3,3'-联吡啶和叠氮化钠在路易斯酸CuSO_4的作用下,得到了一种新型的金属有机铜四唑配合物。X射线单晶衍射结构表明,该化合物属于四方晶系,P4/ncc空间群。它是由吡啶环中的N原子连接形成的无限延展的二维网状结构;硫酸根阴离子位于中心金属周围,且高度无序的硫酸根离子很有可能在低温下变成有序,从而引起结构相变。该化合物的堆积图形状类似一个蝴蝶发卡。其高含氮结构可作为潜在的高含能材料。Hydrothermal reaction of 5,5′-dicyano-3,3′-bipyridyl ligands and sodium azide in the presence of the Lewis acid CuSO 4 in water and ethanol provided a novel metal organic tetrazole complex. X-ray single crystal diffraction analysis shows that this complex belongs to a tetragonal system with P4/ncc space group. This complex displays an interesting infinite two-dimensional(2D) network structure bridge linked by the pyridyl N atoms. The highly disordered sulfate around the central metals are likely to become ordered at low temperatures, leading to structural phase changes. The packing diagram of the crystal structure shows a butterfly hairpin shape. The highly nitrogenated structure allows this complex to be a potential high-energy material .
