CuCN与一组具有不同间隔长度的柔性联吡唑基配体[(dmpz)(CH(2))(n)(dmpz)] （dmpz = 3,5-二甲基吡唑基；n = 1-6）的溶剂热反应生成了六种[CuCN](n)基配位聚合物[(CuCN)(3)L](n) (1: L = dmpzm; 2: L = dmpze), [(CuCN)(2)L](n) （3: L = dmpzpr; 4: L = dmpzb; 5: L = dmpzp; 6: L = dmpzh）。化合物1 ~ 6通过元素分析、红外光谱、粉末x射线衍射和单晶x射线衍射进行了表征。1或2展示了一个由罕见的一维之字形[CuCN](n)链与[CN-Cu-CN-Cu-L] （1: L = dmpzm; 2: L = dmpze）侧臂组装而成的一维类脊柱链。3或4为二维（6,3）波状层，其中[Cu(6)(mu-CN)(6)L(2)](n) （L = dmpzpr或dmpzb）双链由一对L桥相互连接。5由两个[CuCN](n)单链组成，它们通过dmpzp桥连接，形成具有长方形通道的罕见1D链。具有一个3D网络，其中2D [Cu(10)(mu-CN)(10)(dmpzh)(3)](n)层通过dmpzh桥对相互连接。此外，还研究了1-6在室温下的固态光致发光性能。
Solvothermal reactions of CuCN with a set of flexible bipyrazolyl-based ligands with different spacer lengths [(dmpz)(CH(2))(n)(dmpz)] (dmpz = 3,5-dimethyl-pyrazolyl; n = 1-6) gave rise to six [CuCN](n)-based coordination polymers [(CuCN)(3)L](n) (1: L = dmpzm; 2: L = dmpze), [(CuCN)(2)L](n) (3: L = dmpzpr; 4: L = dmpzb; 5: L = dmpzp; 6: L = dmpzh). Compounds 1-6were characterized by elemental analysis, IR, powder X-ray diffraction and single-crystal X-ray diffraction. 1 or 2 exhibits a 1D scolopendra-like chain assembled from a rare 1D zigzag [CuCN](n) chain with [CN-Cu-CN-Cu-L] (1: L = dmpzm; 2: L = dmpze) side arms. 3 or 4 shows a 2D (6,3) wave-like layer in which [Cu(6)(mu-CN)(6)L(2)](n) (L = dmpzpr or dmpzb) double chains are interconnected by pairs of L bridges. 5 consists of two [CuCN](n) single chains that are linked by dmpzp bridges to form a rare 1D chain with an oblong channel. has a 3D network in which the 2D [Cu(10)(mu-CN)(10)(dmpzh)(3)](n) layers are interconnected by pairs of dmpzh bridges. In addition, the photoluminescent properties of 1-6 in the solid state at ambient temperature were investigated.
