Abstract

In the title compound, C14H16N2O8·2H2O, the complete organic molecule is generated by crystallographic inversion symmetry. The dihedral angles between the aniline ring and the acetic acid groups are almost identical, viz. 82.61 (7) and 80.33 (7)°. In the crystal, O—H⋯O hydrogen bonds link the organic mol­ecules and water mol­ecules, forming zigzag chains the c axis. An intra­molecular O—H⋯O hydrogen bond is also observed.
