| 摘要: 以硝酸镉,樟脑酸(H2CAM)和1,3,5-三(1-咪唑基-亚甲基)-2,4,6-三甲基苯(titmb)为原料,采用水热合成的方法得到了一个三维配位聚合物{[Cd2(titmb)(CAM)2]·2H2O}n。通过元素分析、红外光谱以及X-射线单晶洐射对其进行了表征。该晶体属三斜晶系,Pl空间群。Cd(Ⅱ)离子通过CAM配体桥联形成一维链状结构,链与链再通过titmb配体连接成新型三维(4.64.8)2(42.64.89)(62.8)2拓扑的结构。室温下该配合物表现出较强的荧光发射。 |

| Abstract: Anew three-dimensional coordination polymer of {[Cd2(titmb)(CAM)2]·2H2O}n (1) (H2CAM=camphor acid, and titmb=1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene) has been prepared and characterized by elemental analysis, IR spectroscopy, TGAand single-crystal X-ray diffraction. The crystal is of monoclinic, space group Pl with a=1.23825(15) nm, b=1.30128(16) nm, c=1.53729(19) nm, α=91.351 (2)°, β=94.864 (3)°, γ=98.730 (2)°, V=2.4379(5) nm3, Dc=1.386 g·cm-3, Z=2, F(000)=1040, Goof=1.027, R1=0.0545, wR2=0.1210. Complex 1 displays an unusual three-dimensional (3, 4, 6)-connected network with (4.64.8)2(42.64.89)(62.8)2 topology. Moreover, their luminescent properties have been investigated in the solid state.
