A quatridentate bis-amide ligand, N,N'-propylenebis(salicylamide) H2pbs, and its transition metal complexes [M(pbs)(H2O)2], where M=Co(II), Ni(II), Cu(II), and Zn(II) have been synthesized and characterized by elemental analysis, UV-Vis, IR, NMR, Mass, EPR, molar conductivity, magnetic moment values and thermal analysis. The NMR spectrum of ligand evidences the E/Z isomerism. All the evidences reveal that the metal ions adopt octahedral geometry with metal:ligand:solvent ratio 1:1:2. The conductivity measurements exhibit that the complexes are non-electrolytes. DNA binding properties of these complexes have been explored by UV-Vis and cyclic voltammetry. The results indicate that these complexes are good intercalators.
一种四齿双酰胺配体N,N'-亚丙基双（水杨酰胺）H2pbs及其过渡金属配合物[M(pbs)(H2O)2]，其中M = Co(II)、Ni(II)、Cu(II)和Zn(II)，已通过元素分析、紫外可见光谱、红外光谱、核磁共振、质谱、电子顺磁共振、摩尔电导率、磁矩值和热分析进行了合成和表征。配体的核磁共振谱证明了E/Z异构现象。所有证据表明，金属离子采用八面体几何结构，金属:配体:溶剂比例为1:1:2。电导率测量表明这些配合物是非电解质。通过紫外可见光谱和循环伏安法研究了这些配合物的DNA结合特性。结果表明这些配合物是良好的嵌入剂。
