The crystal structures of quinolinium 3-carboxy-4-hydroxybenzenesulfonate trihydrate, C9H8N + C7H5O6S 3H2O, (I), 8-hydroxyquinolinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate, C9H8NO + C7H5O6S H2O, (II), 8-aminoquinolinium 3-carboxy-4-hydroxybenzenesulfonate dihydrate, C9H9N2 + C7H5O6S 2H2O, (III), and 2-carboxyquinolinium 3-carboxy-4-hydroxybenzenesulfonate quinolinium-2-carboxylate, C1...
متن کامل4-Hydroxyanilinium perchlorate dihydrate
In the crystal structure of the title compound, C(6)H(8)NO(+)·ClO(4) (-)·2H(2)O, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds occur. The protonated amine cations and the perchlorate anions are linked through the water mol-ecules, and the hy-droxy groups of the cations and the anions are linked through the water mol-ecules. The cations are connected to the perchlorate anions via inter-molecula...
متن کاملTetrabutylammonium 4-hydroxybenzoate dihydrate
In the title compound, (n-C(4)H(9))(4)N(+)·C(7)H(5)O(3) (-)·2H(2)O, the carboxyl-ate group is twisted slightly out of the plane of the attached benzene ring, the two C-C-C-O torsion angles being -8.9 (2) and -10.7 (2)°. The anion inter-acts with two water mol-ecules through several O-H⋯O hydrogen bonds, forming wide ribbons along the a axis constructed from two anion-water chains. These ribbons...
متن کامل(E)-N′-(4-Ethoxybenzylidene)-4-hydroxybenzohydrazide dihydrate
The benzohydrazide mol-ecule of the title compound, C(16)H(16)N(2)O(3)·2H(2)O, exists in a trans conformation with respect to the C=N double bond. The central O=C-NH-N=C plane [r.m.s. deviation of 0.0165 (1) Å for the five non-H atoms] makes dihedral angles of 6.04 (8) and 2.38 (8)°, respectively, with the hy-droxy- and eth-oxy-substituted benzene rings. The dihedral angle between these benzene...
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...
