Glycinium 3-carboxy-4-hydroxybenzenesulfonate
In the anion of the title salt, C2H6NO2 (+)·C7H5O6S(-), the dihedral angle between the carb-oxy-lic acid group and the benzene ring is 5.02 (12)°. In the crystal, the anions are linked into inversion dimers through pairs of O-H⋯O hydrogen bonds between the carb-oxy-lic acid groups and sulfonate O atoms. A pair of C-H⋯O inter-actions is also observed within each dimer. The anion dimers and the c...

متن کاملMethyl 3-carboxy-5-nitrobenzoate
The structure of the title compound, C(9)H(7)NO(6), is essentially planar [maximum deviation 0.284 (2)Å] except for the methyl H atoms. The crystal structure is stabilized by asymmetric O-H⋯O hydrogen bonds linking the hydrogen carboxyl-ates into pairs around the inversion centres. There is also π-π stacking of the benzene rings [centroid-centroid distance 3.6912 (12) Å].
متن کاملBis[glycinium(0.5+)] perrhenate
All the residues of the title compound, (C(2)H(5.5)NO(2))(2)[ReO(4)], are located in general crystallographic positions. The glycine mol-ecules have usual conformations [Rodrigues Matos Beja et al. (2006 ▶). Acta Cryst. C62, o71-o72] with the H atom of the carboxylate group half-occupied, thus bearing a formal half-positive charge per molecule. The perrhenate anion has nearly ideal tetra-hedral...
متن کاملTransition metal-free one-pot synthesis of 2-substituted 3-carboxy-4-quinolone and chromone derivatives.
A novel one-pot synthesis of the 2-substituted 3-carboxy-4-quinolone/chromone derivatives from readily available 3-oxo-3-arylpropanoates and amides/acyl chlorides is reported, without any transition metal aid.
