2-Amino-terephthalic acid N,N-dimethyl-formamide disolvate.

ABSTRACT: The asymmetric unit of the title structure, C(8)H(7)NO(4)·2C(3)H(7)NO, contains one 2-amino-terephthalic acid and two N,N-dimethyl-formamide mol-ecules. Strong O-H⋯O hydrogen bonds between the acidic carb-oxy H atoms of 2-am-ino-terephthalic acid and the O atoms of both solvent mol-ecules form linear 1:2 complex units. One H atom of the amine group is involved in intra-molecular N-H⋯O hydrogen bonding, whereas the second one takes part in an inter-molecular N-H⋯O connection. Furthermore, the crystal is stabilized by weak C-H⋯O hydrogen bonds.
