X-ray diffraction analysis at room temperature indicates that the complex crystallizes in orthorhombic system, space group P212121 with a = 8.353(1), b = 11.299(2), c = 17.764(2) A, V= 1676.5(4) A3, Z = 4, C14H9CuN5O8, Mr = 438.8, Dc = 1.739 g/cm3, F(000) = 884 and μ(MoKα) = 1.361 mm-1. The final R and wR factors for the observed reflections with I > 2σ(I) are 0.0353 and 0.0855, respectively. R = 0.0432 and wR = 0.0899 for all data. The structure of the title complex consists of a neutral mononuclear entity. The central Cu (II) atom is five-coordinated by two nitrogen donors of one ligand, two unidentate NO3- ions and one CH3CN molecule. The coordination geometry of Cu (II) can be considered as a distorted trigonal bipyramidal configuration. The complex ability of the NO3-ion has more effect than that of the ClO4- ion on the structure of the complex.展开更多

It was observed that hydrazine could enhance the chemiluminescence (CL) intensity of tris-(1,10 phenanthroline)ruthenium(Ⅱ) (Ru( phen)3^2+ )- Cerium( Ⅳ ) ice( Ⅳ )) system, based on which, a novel CL...It was observed that hydrazine could enhance the chemiluminescence (CL) intensity of tris-(1,10 phenanthroline)ruthenium(Ⅱ) (Ru( phen)3^2+ )- Cerium( Ⅳ ) ice( Ⅳ )) system, based on which, a novel CL system, Ru(phen)3^2+ Hydrazine-Ce(Ⅳ), was established. This CL system was investigated and employed to detect hydrazine. Under the optimum experimental conditions, the linear range and detection limit of the proposed method are 2.0× 10^-6-2.0×10^-3g·L^-1 and 1. 8×10^-6g·L^-1, respectively. For 1. 5 × 10^-5, 1.5×10^-4 and 1.2×10^-3 g·L^-1 hydrazine, the relative standard deviation (RSD) is 2.9%, 2.2% and 3. 1%, respectively (n= 11). The proposed method has been used to detect the content of hydrazine in the synthetic samples with satisfactory results.展开更多
