2-Phenylimidazolium nitrate monohydrate
In the title hydrated mol-ecular salt, C(9)H(9)N(2) (+)·NO(3) (-)·H(2)O, the dihedral angle between the aromatic rings in the cation is 11.09 (8)°. In the crystal, the components are linked into chains propagating in [101] by N-H⋯O and O-H⋯O hydrogen bonds.
متن کامل9-Aminoacridinium nitrate monohydrate
The pyridine N atom of the cation in the title hydrated salt, C(13)H(11)N(2) (+)·NO(3) (-)·H(2)O, is protonated; the N atom of the NH(2) group shows a planar conformation. The former N atom is hydrogen bonded to a water mol-ecule. The amino group is involved in three N-H⋯O hydrogen bonds with two neighboring nitrate anions. The water mol-ecule is hydrogen bonded to two adjacent nitrate anions. ...
متن کامل4-Acetamidoanilinium nitrate monohydrate
In the title hydrated salt, C(8)H(11)N(2)O(+)·NO(3) (-)·H(2)O, the N-C bond distances [1.349 (2) and 1.413 (2) Å] along with the sum of the angles (359.88°) around the acetamide N atom clearly indicate that the heteroatom has an sp(2) character. The ammonium group is involved in a total of three N-H⋯O hydrogen bonds, two of these are with a water mol-ecule, which forms two O-H⋯O hydrogen bonds....
متن کامل8-(Carboxymethoxy)quinolinium nitrate monohydrate
In the title compound, C(11)H(10)NO(3) (+)·NO(3) (-)·H(2)O, the planar 8-carboxy-methoxy-quinolinium cation, the nitrate anion and the water mol-ecule are dimerized by hydrogen bonds into square building-block units, and then further assembled into two-dimensional gently undulating supra-molecular layers.
متن کاملBis(2,6-diaminopyridinium) hydrogen phthalate nitrate monohydrate
The title hydrated salt, 2C(5)H(8)N(3) (+)·C(8)H(5)O(4) (-)·NO(3) (-)·H(2)O, was obtained fortuitously from the reaction between 2,6-diamino-pyridine, phthalic acid and Co(NO(3))(2)·6H(2)O at 343 K. The asymmetric unit consists of two crystallographically independent 2,6-diamino-pyridinium cations, a hydrogen phthalate anion, a nitrate ion and a water mol-ecule of crystallization which in the c...
