2-Amino-4-methylpyridinium 2-hydroxy-3,5-dinitrobenzoate
In the anion of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36 (10) and 4.86 (11)°. The anion is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-H⋯O and C-H⋯O inter-actions and are furthe...

In the title compound, C(14)H(13)ClN(+)·I(-)·H(2)O, the cation is nearly planar and exists in an E configuration; the dihedral angle between the pyridinium and benzene rings is 0.98 (17)°. The cations stack in an anti-parallel manner along the a axis through two π-π inter-actions between the pyridinium and benzene rings [centroid-centroid distances 3.569 (2) and 3.6818 (13) Å, respectively]. Th...
متن کامل2-[(E)-2-(4-Hydroxy-3-methoxyphenyl)ethenyl]-1-methylpyridinium 4-bromobenzenesulfonate monohydrate
The title salt crystallized as the monohydrate C15H16NO2 (+)·C6H4BrSO3 (-)·H2O. The cation exists in an E conformation with respect to the ethynyl bond and is essentially planar, with a dihedral angle of 6.52 (14)° between the pyridinium and the benzene rings. The hy-droxy and meth-oxy substituents are coplanar with the benzene ring to which they are attached, with an r.m.s. deviation of 0.0116...

In the title compound, C(10)H(9)N(3)O, the organic rings linked to the ether O atom make a dihedral angle of 76.8 (1)° and the C-O-C angle is widened to 119.07 (15)°. In the crystal, adjacent mol-ecules are connected by an N-H⋯N hydrogen bond, generating a chain running parallel to the b axis. The crystal is a non-merohedral twin with a ratio of twin components of 0.508 (3):0.492 (3).
متن کامل4-Amino-2-hydroxybenzohydrazide
The asymmetric unit of the title compound, C(7)H(9)N(3)O(2), comprises two crystallographically independent mol-ecules (A and B). In each mol-ecule there is an intra-molecular O-H⋯O hydrogen bond making an S(6) ring motif. In the crystal, a pair of N-H⋯N hydrogen bonds link the two mol-ecules (A and B) into a dimer with an R(2) (2)(6) ring motif. The B mol-ecules are linked via pairs of N-H⋯O h...
