| 摘要: 由联苯-2，4，4'，6-四甲酸（H4BPTC，C16H10O8）和2-4-（1H-咪唑-2-[4，5-f][1，10]菲啰啉基）苯氧乙酸（HPIMPHC，C21H14N4O3），水热合成了2种新型配位聚合物[Ag4（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。 |

| Abstract: Two novel coordination polymers[Ag4(BPTC)]n (1) and[Cd(PIMPHC)2]n (2) were synthesized under hydrothermal reactions by using biphenyl-2,4,4',6-tetracarboxylic acid (H4BPTC, C16H10O8) and 2-(4-(1H-imidazo-2-[4,5-f] [1,10]phenanthrolinyl)phenoxy) acetic acid (HPIMPHC, C21H14N4O3). They were characterized by elemental analysis, IR spectra, TGA, single crystal X-ray diffraction. Complex 1 crystallizes in triclinic system with space group P1, the coordination numbers of Ag(Ⅰ) are four, three and two, forming distorted tetrahedron, flat triangular and V-type coordination geometry. Complex 2 crystallizes in orthorhombic system with space group Pbcn, Each Cd(Ⅱ) is bridged by the PIMPHC- anions, forming a distorted octahedral coordination geometry. The interaction of complexes, ligands and ct-DNA were studied by EtBr fluorescence probe. |
