C 91 Crystal structure of copper(II) chelate with para-(tert-butyl)benzoic acid N′,N′-dimethylhydrazide / V. Yu. Gusev, D. A. Muksinova, P. A. Slepukhin, A. V. Radushev // Russian Journal of Coordination Chemistry. - 2012. - Vol.38, №8. - С. 515-518 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CRYSTAL STRUCTURE -- N′,N′-DIMETHYLHYDRAZIDE -- BENZOIC ACID Аннотация: X-Ray diffraction analysis was performed for the copper(II) chelate with para-(tert-butyl)benzoic acid N′,N′-dimethylhydrazide, Cu(p-(tert-Bu)C6H4CONHNMe2)2 (I). The reagent functions as a bidentate (O,N(2)) ligand giving a five-membered copper-containing ring. The molecule is centrosymmetric. The Cu atom and the metal rings lie in the same plane. The coordination polyhedron of copper is a slightly distorted square. The crystals are monoclinic: a = 16.2634(14) Å, b = 9.0415(8) Å, c = 9.6415(9) Å, α = 90°, β = 100.052(7)°, Z = 2, space group P21/c. \\\\Expert2\\nbo\\Russian Journal of Coordination Chemistry\\2012, v. 38, N. 8, p.515.pdf |
