Synthesis and structure of 5-[(4-fluorobenzyl)amino]isophthalic acid featuring O—H⋯O and N—H⋯π interactions

Abstract

In the title compound, the dihedral angle between the aromatic rings is 77.78 (8)°. In the crystal, the molecules are linked into zigzag ribbons propagating along the [210] direction by pairwise O—H⋯O hydrogen bonds through their two carboxylic acid groups to generate centrosymmetric R22(8) dimers in each case. In addition, molecules are connected via pairwise N—H⋯π interactions between the NH groups and the fluorobenzene rings.
