金属离子导向自组装的磺酰化对氨基苯甲酸配合物的合成与表征

用普通溶液法合成了4个配合物:[Cu(Ts-p-aba)2(phen)(H2O)]n(1)、[Zn(Ts-p-aba)2(phen)(H2O)]·H2O(2)、[Pb(Ts-p-aba)2(phen)]2(3)和{[Pb(Ts-p-aba)(phen)(NO3)](DMF)}n(4)(Ts-p-aba=N-对甲苯磺酰对氨基苯甲酸,phen=菲咯啉,DMF=N,N-二甲基甲酰胺)。X-射线单晶衍射结果表明:配合物1和2均为三斜晶系,P1空间群。配合物1的中心铜离子处于变形的八面体配位环境,并通过配体N-对甲苯磺酰对氨基苯甲酸扩展为一维直线链结构;配合物2是个单核分子,锌离子的配位多面体为四角锥体。配合物3和4均为单斜晶系,P21/c空间群。配合物3由配体N-对甲苯磺酰对氨基苯甲酸桥联成二聚体,铅离子处于变形的八面体配位环境;配合物4是具有一维链状结构的配位聚合物,铅离子处于变形的一面心八面体配位环境。另外,对4个配合物的热稳定性、电化学性能和荧光性质也进行了研究。

Synthesis and Characterization of Metal-Directed Assembly of Complexes with N-p-Tolylsulfonyl-p-Aminobenzoic Acid

Four complexes, [Cu(Ts-p-aba)₂(phen)(H₂O)]_n (1), [Zn(Ts-p-aba)₂(phen)(H₂O)]·H₂O (2), [Pb(Ts-p-aba)₂(phen)]₂ (3), and {[Pb(Ts-p-aba)(phen)(NO₃)](DMF)}_n (4) (Ts-p-aba=N-p-Tolylsulfonyl-p-Aminobenzoic acid, phen=1,10-phenanthroline, DMF=N,N-dimethyl formamide), were synthesized using a common solution method. Their crystal structures were determined by single-crystal X-ray diffraction. Complexes 1 and 2 are of triclinic system, and belong to space group P1 The central Cu²⁺ ion of complex 1 is in a distorted octahedral position and shows a one-dimensional chain bridged by N-p-Tolylsulfonyl-p-Aminobenzoic acid. The complex 2 is a mononuclear-molecule. The coordination polyhedron of Zn²⁺ ion is distorted square pyramidal. Complexes 3 and 4 are of monoclinic system, with space group P2₁/c. The complex 3 is a dipolymer linked by N-p-Tolylsulfonyl-p-Aminobenzoic acid. The Pb²⁺ ion is in a geometry of distorted octahedral. Complex 4 has a one-dimensional chain with a distorted one-face-centered octahedral environment. Further, TGanalysis, cyclic voltammetric behavior, and fluorescent properties of the four complexes were investigated. CCDC: 968877, 1; 824654, 2; 939749, 3; 939748, 4.
