以1-(4-咪唑基)-4-(四氮唑)苯(HL)与对苯二甲酸(H_2pbda)或间苯二甲酸(H_2mbda)作为混合配体,与硫酸锌进行水热合成反应,构筑了2个新的金属配位配合物[Zn_2(L)_2(pbda)]n(1)和[Zn_2(L)_2(mbda)]_n(2),并进行了元素分析、红外、热重、X射线粉末衍射及单晶衍射等表征。晶体结构分析表明:配合物1结构中,去质子化的L-与锌离子结合成[Zn_2(L)_2]~(2+)的二维结构,相邻的二维层由pbda~(2-)配体连接成二重贯穿层柱状的具有dmc拓扑的三维结构,拓扑符号为(4·82)(4·85);配合物2是由2个羧酸基团与锌离子形成的双核[Zn_2(COO)_2]为基本单元连结而成的单一6连结具有(412·63)-pcu拓扑的三维结构。同时,对配合物1和2在室温下的固体荧光性质进行了研究。
The hydrothermal synthesis reaction of zinc sulfate with zinc (II) and hydrogen (H_2pbda) or isophthalic acid (H_2mbda) was carried out using 1- (4-imidazolyl) -4- , Two new metal coordination complexes [Zn_2 (L) _2 (pbda)] n (1) and [Zn_2 (L) _2 (mbda)] _n (2) were constructed and characterized by elemental analysis, Thermogravimetry, X-ray powder diffraction and single crystal diffraction characterization. The crystal structure analysis shows that in the structure of complex 1, the deprotonated L- and zinc ions combine into the two-dimensional structure of [Zn_2 (L) _2] ~ (2+). The adjacent two- -) ligand connected into a double through the columnar dmc topology of the three-dimensional structure, the topological symbols (4.82) (4.85); complex 2 is composed of two carboxylic acid groups and zinc ions formed dual-core [Zn_2 (COO) _2] is a three-dimensional structure in which a single 6-connected basic unit has a (412 · 63) -pcu topology. Meanwhile, the solid fluorescence properties of complexes 1 and 2 at room temperature were studied.
