The mixed ligand complex [Pd(biqu)(pmal)]·H2O (where biqu is 2,2′-biquinoline, pmal is phenethylmalonate) has been synthesized and its interaction with sperm DNA was determined by fluorescent spectra、 UV-Vis spectra and CD-spectra. The binding constant (Kb) of the complex and sperm DNA is 1.26×104 and its interaction with pBR322 plasmid DNA was also determined by gel electrophoresis. The results show that the complex interact with DNA mainly by intercalative mode. 相似文献

A novel ligand N-ethyl-1,10-phenanthroline-2-methanamine and its Ni(Ⅱ) complex have been synthesized. The crystal structure of the complex has been determined by X-ray diffraction method. The Ni(Ⅱ) is five-coordinated by three nitrogen atoms from the ligand and two Cl- anions in a distorted trigonal bipyramidal environment: the N(2), Cl(1) and Cl(2) in equatorial plane; the N(1) and N(3) in axial positions. The UV-spectra and IR-spectra of the ligand and its Ni(Ⅱ) complex were recorded and discussed. The thermodynamic properties of the ligand with various bivalent metals were studied by potentiometric titrations and the order of the stability constants is in agreement with the Irving-Williams order in coordination chemistry.

Dark red single crystals of AgCuVO4 were obtained from hydroxide fluxes in Ag‐containers at 430 °C. According to X‐ray diffraction data AgCuVO4 crystallizes in the orthorhombic space group Pnma (Z = 4, a = 925.5(1) pm, b = 677.8(1) pm, c = 540.1(1) pm, wR2 = 0.0753). The Pearson code (oP28) and Wyckoff sequence (dc4a) indicate that AgCuVO4 is related to the olivine‐type of structure, but the first coordination sphere of AgI and CuII differ significantly from the C.N. 6 with irregular square‐pyramidal [AgO5] polyhedra and distorted square‐planar [CuO4] units. These differences in crystal chemistry are discussed and MAPLE as well as ECoN values are given. 相似文献
