Aqua{μ-N-[3-(dimethylamino)propyl]-N′-(2-oxidophenyl)oxamidato(3−)}(1,10-phenanthroline)dicopper(II) nitrate
The title complex, [Cu2(C13H16N3O3)(C12H8N2)(H2O)]NO3, consists of a nitrate ion and a binuclear CuII unit in which the oxamide ligand has a cis geometry, is fully deprotonated and acts in a bidentate fashion to one CuII atom and in a tetradentate fashion to the other CuII atom. The CuII atom coordination geometries are distorted square-planar and distorted square-pyramidal. In the crystal structure, binuclear complexes and nitrate ions are connected by classical O—H⋯O and non-classical C—H⋯O hydrogen bonds into a three-dimensional framework. The alkyl chains of the anion are equally disorded over two positions
[N′-(3-Methoxy-2-oxidobenzylidene)nicotinohydrazidato]dimethyltin(IV)
In the title complex, [Sn(CH3)2(C14H11N3O3)], the Sn atom is in a distorted trigonal-bipyramidal coordination, with Sn—O distances of 2.138 (2) and 2.176 (2) Å. The dihedral angles between the two chelated benzene rings and the O—Sn—N group are 71.73 (9) and 83.30 (9)°
Design and development of infrastructure of the Dome A Kunlun Station (2005–2015)
To enable further advanced study of Antarctica, a new station called Kunlun Station has been built by China in the Dome A region of the inland East Antarctic ice sheet. This paper describes the Antarctic station building design system that was developed with consideration of factors that may affect Kunlun Station, such as environment and climate, construction work and transport, environmental protection and energy conservation, psychological requirements and functional requirements. The design system included site selection, station planning, external building form, construction work, function and indoor environment, energy conservation, environmental protection, and material strategy. We also describe the experience acquired during the transportation and construction phases of Kunlun Station
