摘要
在溶剂热条件下,以自制的柔性1,6-双(苯并三氮唑)己烷(BBTH)为桥联配体,以溴离子为第二桥联配体与过渡金属Cu(I)合成了一个结构新颖的配位聚合物:{[CuBr]2(BBTH)}n(1),通过元素分析、X-射线粉末衍射、红外光谱、固体荧光光谱、热重分析对其结构和性质进行了表征和研究,用X-射线单晶衍射测定了该配合物的晶体结构。晶体属于四方晶系,空间群为I4(1)/a,晶胞参数a=b=18.0352(18)A,c=13.6749(13)A,V=4448.0(8)A3,Z=8。结果分析表明,中心铜原子与两个来自配体中的氮原子和两个桥联溴原子进行配位,形成一个变形的四面体配位模式。该配合物中两个溴原子以μ2-桥联模式连接相邻的两个铜原子构成一维Z形无机链,进而配体(BBTH)采取μ4-桥联的模式连接该Z形无机链形成无限的三维结构。
The solvothermal reaction of the flexible ligand 1,6-bi(benzotriazole)hexane (BBTH) with CuBr generated a novel three-dimensional hybrid solid, namely, {[CuC1]2(BBTH)}n, which was done through element analysis, FT-IR, X-ray powder diffraction (XRPD), X-ray single-crystal diffraction, TG/DTA and photoluminescence measurements.2t crystallizes in the tetragonal system, space group I4 (1)/a, a =b =18.0352 (18) A ,c =13.6749 (13) A ,V =4448.0 (8) /k3, Z=8. The distorted tetrahedral geometry of Cu (I) is defined by two Br atoms and two N donors from different BBTH ligands. Adjacent copper atoms are firstly connected by /x2-Br to give 1D zigzag inorganic chain, which are further linked by BBTH ligands via unique I.~4-bridging mode, forming the 3D hybrid structure of {[CuBr]2(BBTH)}..
