| 英文摘要 | A new ligand, 2-(2-hydroxyphenyl)-5,6-dichlorobenzimidazole, H(2)pbmCl(2) (1), and a novel Mn-III complex, [Mn-III(HpbmCl(2))(pbmCl(2))(DMF)(2)] (2), (DMF = N,N-dimethylformamide), have been synthesized and characterized. The crystal of compound 1 (C13H8Cl2N2O, M-r = 279.12) belongs to the monoclinic system, space group P2(1) with a = 3.770(5), b = 25.20(3), c = 5.865(7) angstrom, beta = 92.727(17)degrees, V = 556.6(12) angstrom(3), Z = 2, D-c = 1.665 g/cm(3), S= 1.137, mu = 0.568 mm(-1), F(000) = 284, the final R = 0.0876 and wR = 0.2334 for 1848 independent reflections. The molecule is planar due to the presence of a strong intrainolecular hydrogen bond between O-H group of phenol and N atom of imidazole. H(2)pbmCl(2) (1) molecules are arranged into a one-dimensional linear chain through intermolecular hydrogen bonds (N-H center dot center dot O and C-H center dot center dot center dot Cl). The crystal of complex 2 (C32H27Cl4MnN6O4, M-r = 756.34) belongs to the monoclinic system, space group P2(1)/c with a = 19.043(10), b = 10.808(5), c = 18.704(11) angstrom, beta = 115.540(6)degrees, V = 3473(3) angstrom(3), Z = 4, D-c = 1.446 g/cm(3), S = 1.3 mu = 0.733 mm(-1), F(000) = 1544, the final R = 0.1219 and wR = 0.2681 for 7811 independent reflections. The Mn ion adopts a distorted octahedral geometry coordinated by two deprotonated H(2)pbmCl(2) ligands and two DMF molecules. The [Mn-III(HpbmCl(2))(pbmCl(2))(DMF)(2)] molecules are arranged into a three-dimensional structure through hydrogen bonds (N-H center dot center dot center dot N, C-H center dot center dot center dot N and C-H center dot center dot center dot Cl) and weak pi...pi interactions. The activity measurements suggest that complex 2 is able to serve as a catalyst for H2O2 disproportionation reaction to form O-2 in neutral water solution. |
