2-(Methoxycarbonyl)anilinium dihydrogen phosphate

Abstract

The title compound, C8H10NO2 +·H2PO4 −, is a derivative of the naturally occurring compound methyl­anthranilate. The asymmetric unit comprises the 2-(methoxy­carbon­yl)anilinium cation and the dihydrogen phosphate anion. In the cation, the dihedral angle between the benzene ring plane and that through the methyl ester substituent is 22.94 (9)°. In the crystal, adjacent cations and anions form dimers through N—H⋯O and O—H⋯O hydrogen bonds, respectively. Additional N—H⋯O and C—H⋯O contacts result in a network of cation and anion dimers stacked down the b axis.

Dihydrogen phosphate mediated supramolecular frameworks in 2- and 4-chloroanilinium dihydrogen phosphate salts

“…In 2CADHP, the formation of an anionic double-stranded substructure and the linking of the cations to it is analogous with other reported structures. In the crystal structures of 2,4dimethylanilinium dihydrogen phosphate (Fá bry et al, 2001), 2-(methoxycarbonyl)anilinium dihydrogen phosphate (Shafiq et al, 2009) and 3,5-dimethoxyanilinium dihydrogen phosphate (Kaabi et al, 2004) (Z 0 = 2Z), the respective cations bound to the anionic substructures form two-dimensional sheets. In the last compound, the substructure was formed with different ring motifs than the other two structures.…”

Synthesis, growth, structure and nonlinear optical properties of a semiorganic 2-carboxy pyridinium dihydrogen phosphate single crystal

“…The hydrogen bond network in 2-carboxy pyridinium dihydrogen phosphate is mainly stabilized by the presence of strong NAHÁ Á ÁO and OAHÁ Á ÁO hydrogen bonds as observed in most of dihydrogen phosphate salts [21][22][23][24]. Also the presence of CAHÁ Á ÁO interaction contributes the formation of molecular binding in the crystalline solid.…”
