由联苯-2,4,4′,6-四甲酸(H_4BPTC,C_(16)H_(10)O_8)和2-4-(1H-咪唑-2-[4,5-f][1,10]菲啰啉基)苯氧乙酸(HPIMPHC,C_(21)H_(14)N_4O_3),水热合成了2种新型配位聚合物[Ag_4(BPTC)]_n(1),[Cd(PIMPHC)_2]_n(2)。用元素分析、红外光谱、热重分析和X射线单晶衍射对配合物进行了表征和结构分析。配合物1属三斜晶系,空间群为P1;Ag(Ⅰ)的配位数分别为4、3、2,配位构型为变形四面体、平面三角形和V型。配合物2属正交晶系,空间群为Pbcn;Cd(Ⅱ)的配位数为6,配位构型为变形的八面体,Cd(Ⅱ)离子间通过三齿配体PIMPHC-桥连,形成2D网状结构。用EtBr荧光探针法研究了配体及配合物与ct-DNA的相互作用。
(H_4BPTC, C_ (16) H_ (10) O_8) and 2-4- (1H-imidazole-2- [4,5-f] [1, (HPIMPHC, C_ (21) H_ (14) N_4O_3]) were synthesized by hydrothermal method. Two new coordination polymers [Ag_4 (BPTC)] _ n ) _2] _n (2). The complex was characterized and analyzed by elemental analysis, IR, TG and X-ray single crystal diffraction. The complex 1 belongs to the triclinic system with space group P1. The coordination numbers of Ag (Ⅰ) are 4, 3 and 2, respectively. The coordination structures are deformed tetrahedron, plane triangle and V-shape. The complex 2 belongs to the orthorhombic crystal system, and the space group is Pbcn. The coordination number of Cd (Ⅱ) is 6 and the coordination configuration is distorted octahedron. The Cd (Ⅱ) , Forming a 2D network structure. The interaction between ligands and their complexes with ct-DNA was studied by EtBr fluorescence probe.
