Crystal structure of poly[[trans-diaquabis[μ2-trans-4,4′-(diazenediyl)dipyridine]nickel(II)] diiodide ethanol disolvate]
In the title compound, {[Ni(C10H8N4)2(H2O)2]I2·2C2H5OH} n , the complex shows an octa-hedral environment of the Ni(2+) cation in which it is located on a centre of symmetry, linked to two water mol-ecules and the pyridine-N atoms of four 4,4'-(diazenediyl)dipyridine ligands bridging Ni(2+) cations along the b- and c-axis directions, giving rise to a two-dimensional arrangement. The Ni-N bond le...
متن کاملCrystal structure of rubidium peroxide ammonia disolvate
The title compound, Rb2O2·2NH3, has been obtained as a reaction product of rubidium metal dissolved in liquid ammonia and glucuronic acid. As a result of the low-temperature crystallization, a disolvate was formed. To our knowledge, only one other solvate of an alkali metal peroxide is known: Na2O2·8H2O has been reported by Grehl et al. [Acta Cryst. (1995), C51, 1038-1040]. We determined the pe...
متن کاملCrystal structure of (±)-[trans-cyclohexane-1,2-diylbis(azanediyl)]diphosphonium dibromide dichloromethane disolvate
The cation of the title solvated salt, C42H42N2P2 (2+)·2Br(-)·2CH2Cl2, lies on a crystallographic twofold rotation axis. The 1,2-di-amino-cyclo-hexane fragment has a chair conformation with two N atoms in a transoid conformation [N-C-C-N = 163.4 (2)°]. In the crystal, the cations are linked to the anions by N-H⋯Br and C-H⋯Br hydrogen bonds, forming a chain structure along the c axis. The di-chl...
متن کاملCrystal structure of 1-(2,4-dimethylphenyl)urea
In the title urea derivative, C9H12N2O, the dihedral angle between the benzene ring and the mean plane of the urea group, N-C(=O)-N, is 86.6 (1)°. In the crystal, the urea O atom is involved in three N-H⋯O hydrogen bonds. Mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked by further N-H⋯O hydrogen bonds, forming...
متن کاملCrystal structure of N-[(methylsulfanyl)carbonyl]urea
The almost planar (r.m.s. deviation = 0.055 Å) title compound, (MeS)C(O)NHC(O)NH2, was formed during an attempted crystallization of dimethyl cyano-carbonimidodi-thio-ate with CrO2Cl2; an unexpected redox reaction converted the cyano-carbonimido moiety to a urea group and removed one methyl-thiol group. In the crystal, hydrogen-bonding inter-actions from the amide and amido N-H groups to carbon...
