| Abstract: A new nickel(Ⅱ) complex: [Ni(tribentacn)](ClO4)2, (tribentacn=1,4,7-tris-(benzimidazole-2-yl-methyl)-1,4,7-triazacyclononane), has been synthesized and characterized by elemental analysis and IR spectra. The crystal structure of this complex was determined by X-ray diffraction analysis, crystallized in the triclinic system, space group P1, Z=2, a=1.208 01(8) nm, b=1.217 66(8) nm, c=1.281 42(8) nm, α=78.809(3)°, β=77.094(2)°, γ=66.460(3)°, R1=0.078 0. The nickel(Ⅱ) atom is octahedrally coordinated by six nitrogen atoms of three benzimidazoles and 1,4,7-triazacyclononane (tacn). The electrochemical property and interactions with pBR322 DNA of the complex were studied. CCDC: 841482. |
