【摘要】 CdSO4·8/3H2O与5-氨基四唑-1-乙酸(Hatza)(Hatza=5-aminotetrazole-1-acetic acid)及4,4′-联吡啶(4,4’-bipy)在水和乙醇的混合溶液中反应,生成了一个新的配合物[Cd(atza)2(4,4’-bipy)0.5(H2O)].通过元素分析,红外光谱和X-射线单晶衍射对此配合物进行了表征.该配合物晶体结构属单斜晶系,主要晶体结构数据:空间群P21/c,a=10.356(2),b=13.482(3),c=13.230(3)?,β=111.18(3)(°).在此晶体中,Cd(II)与两个来自atza配体的两个氧原子、两个来自atza配体的两个氮原子、一个水分子的一个氧原子及一个4,4’-bipy配体的一个氮原子配位,配位数为6,配位构型为变形的八面体.每个atza作为双齿配体与两个Cd(II)配位,通过atza和4,4’-联吡啶配体的桥联作用,该配合物形成了沿bc面伸展的二维结构.相邻的面之间通过氢键作用,形成了三维结构.此外,在室温下研究了配合物固体荧光特性.更多还原

【Abstract】 A reaction of CdSO4 with Hatza(Hatza=5-aminotetrazole-1-acetic acid) and 4,4’-bipy, produced anew coordination compound [Cd(atza)2(4,4’-bipy)0.5(H2O)]. This compound was structurally characterized by ele-mental analysis, IR and single-crystal X-ray diffraction. It crystallizes in monoclinic space group P21/c. Crystalparameters: a=10.356(2), b=13.482(3), c=13.230(3)?, β=111.18(3)(°). Each Cd center is six-coordinated by twooxygen atoms from two atza ligands, one oxygen atom from one water molecule and two nitrogen atoms from atzaligand and 4,4’-bipy ligand, respectively, forming a distorted octahedral coordination geometry. This compounddisplays a 2D layer network via the bridging mode of atza and 4,4’-bipy ligands and further generates a 3D net-work through hydrogen bonding interactions. Furthermore, the luminescence properties were also investigated atroom temperature in the solid state.更多还原
