Crystal structure of rac-3-hydroxy-2-(p-tolyl)-2,3,3a,4,7,7a-hexahydro-1H-4,7-methanoisoindol-1-one
(International Union of Crystallography, 2015)
In the title compound, C16H17NO2, the cyclohexene ring adopts a boat conformation, and the five-membered rings have envelope conformations with the bridging atom as the flap. Their mean planes are oriented at a dihedral ...
Ethyl 2-[(2-hydroxybenzylidene)amino]-6-methyl-4,5,6,7-tetrahydrothieno[2, 3-c]pyridine-3-carboxylate
(2013)
The title compound, C18H20N2O3S, exists as the phenol–imine form in the crystal and there are bifurcated intramolecular O—H…(N/O) hydrogen bonds present. The conformation about the C N bond is anti (1E); the C N imine bond ...
4-[2-(2,2-Dimethyl-4,6-dioxo-1,3-dioxan-5-ylidene)hydrazin-1-yl] benzo-nitrile
(2010)
In the title compound, C 13H 11N 3O 4, the dioxane ring adopts an envelope conformation with the C atom bonded to the dimethyl group in the flap position [deviation = 0.613 (1) Å]. The nitrile group and the attached benzene ...
Tetraaquabis(orotato-O)cobalt(II) dihydrate
(2010)
In the title CoII complex, [Co(C5H3N 2O4)2(H2O)4]·2H2O, the CoII ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water mol-ecules ...

(2010)
The asymmetric unit of the title complex, [Zn(C8H 7O3)2(C6H6N 2O)2], contains three crystallographically independent molecules with similar configurations. The ZnII cation is coordinated by two N atoms of two nicotinamide ...
Phase transition and elasticity of gallium arsenide under pressure
(Universidade Federal de Sao Carlos, 2014)
Geometry optimization calculations were performed for some structural, elastic and mechanical properties of gallium arsenide (GaAs) under pressures up to 25 GPa. In contrast to previous works, a recent Stillinger-Weber ...
Geometry optimization calculations for the elasticity of gold at high pressure
(2013)
We present embedded atom method based geometry optimization aspects of pressure effect on some elastic and mechanical properties of gold. During study, we determined the pressure dependency of equilibrium volume, typical ...
Magnetism and microstructure characterization of phase transitions in a steel
(2014)
We present phase transitions in a low carbon steel according to existing phases and their magnetism. Scanning electron microscope employed research to clarify and evaluate the microstructural details. Additionally, we ...
