Hexaaquacobalt(II) bis(5-acetyl-2-hydroxybenzoate) dihydrate
In the title compound, [Co(H(2)O)(6)](C(9)H(7)O(4))(2)·2H(2)O, the Co(2+) cation lies on a twofold rotation axis and is coordinated by six water mol-ecules in a distorted octa-hedral geometry. In the 5-acetyl-2-hy-droxy-benzoate anion, the hy-droxy group links with the carboxyl-ate group via an intra-molecular O-H⋯O hydrogen bond and the acetyl group is twisted to the benzene ring at a dihedral...
متن کامل4-Methoxyquinolinium-2-carboxylate dihydrate
The title hydrated quinoline derivative, C(11)H(9)NO(3)·2H(2)O, crystallizes as a zwitterion in which the quinoline N atom is protonated. The quinoline ring is essentially planar, with a maximum deviation of 0.017 (2) Å. An intra-molecular N-H⋯O hydrogen bond between the protonated N atom and the O atom of the carboxyl-ate group in the zwitterion forms an S(5) ring motif. In the crystal, the zw...
متن کاملBis(2-methylimidazolium) fumarate dihydrate
In the title compound, 2C(4)H(7)N(2) (+)·C(4)H(2)O(4) (2-)·2H(2)O, the asymmetric unit consists of one 2-methyl-imidazolium cation, half a fumarate dianion and one water mol-ecule. There is an inversion center at the mid-point of the central C-C bond of the fumarate anion. In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular N-H⋯O, O-H⋯O and weak C...
متن کامل2-Aminopyridinium 4-methylbenzoate dihydrate
The crystal structure of the title salt, C(5)H(7)N(2) (+)·C(8)H(7)O(2) (-)·2H(2)O, contains a three-dimensional supra-molecular framework constructed through N-H⋯O and O-H⋯O hydrogen bonds.
متن کامل2-Acetyl-1,1,3,3-tetramethylguanidine
In the mol-ecule of the title compound, C(7)H(15)N(3)O, the central C atom is surrounded in a nearly ideal trigonal-planar geometry by three N atoms. The C-N bond lengths in the CN(3) unit are 1.3353 (13), 1.3463 (12) and 1.3541 (13) Å, indicating an inter-mediate character between a single and a double bond for each C-N bond. The bonds between the N atoms and the terminal C-methyl groups all h...
