In the crystal struture of the title compound, C(16)H(14)O(6)·C(3)H(7)NO, the two crystallographically independent benzene rings are coplanar [dihedral angle = 1.00 (2)°]. The crystal structure is stabilized by O-H⋯O hydrogen bonds between the diacid and the solvate dimethylformamide mol-ecule, resulting in the formation of a zigzag chain structure extending parallel to [001].
在标题化合物C(16)H(14)O(6)·C(3)H(7)NO的晶体结构中,两个晶体学独立的苯环是共面的[二面角 = 1.00 (2)°]。晶体结构通过二酸与溶剂化二甲基甲酰胺分子之间的O—H⋯O氢键得以稳定,从而形成平行于[001]延伸的锯齿链结构。
