In the title hydrated mol-ecular salt, [Mg(H(2)O)(6)](C(13)H(9)BrNO(4)S)(2)·2H(2)O, the Mg(2+) ion (site symmetry ) adopts a near regular MgO(6) octa-hedral coordination geometry. In the anion, the dihedral angle between the aromatic rings is 2.5 (2)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, the components are linked by O-H⋯O and O-H⋯Br hydrogen bonds.

In the title salt, C(6)H(9)N(2) (+)·C(6)H(7)O(2) (-)·2H(2)O, the non-H atoms of the 2-amino-4-methyl-pyridinium cation are coplanar, with a maximum deviation of 0.010 (1) Å. In the crystal structure, the pyridinium N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The sor...

The cation of the title salt, C(18)H(20)N(4) (2+)·2HSO(4) (-)·2H(2)O, lies on a center of inversion with the mid-point directly in the middle of the p-phenyl-ene ring. Within the hydrogensulfate ion, the S-O(H) bond is the longest of the S-O bonds. The dihedral angle between the central and terminal ring of the cation is 78.6 (2)°. In the crystal, the cation, anion and water mol-ecule inter-act...
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...
