【Abstract】 A new tripodal ligand, 1,1,1 tris(3 (2 benzimidazole) 2 oxa propyl)propane (L), and its complex with Ni(NO 3) 2 have been synthesized, and its crystal structure was determined by single crystal X ray structure analysis. The crystal belongs to monoclinic system, P 2 1/ n space group with a =1.2151(4) nm, b =1.5535(5) nm, c =2.1740(7) nm, β =90.551(18)°, V =4.103(2) nm 3, Z =4, M r=834.03, R = 0.0556 , wR =0.1256, μ =0.541 mm -1 , F (000)=1758 for 7091 unique reflections. The complex cation 2+ has a distorted octahedral geometry. Each cation is formed through six coordinations to Ni 2+ of all three pairs of oxygens and nitrogens from the ligand.更多还原
