چکیده
The asymmetric unit of title compound, C(8)H(6)O(4)·2C(4)H(9)NO, contains one half-mol-ecule (an inversion centre in P21/n generates the other half of the molecule) of terephthalic acid (TA) and one mol-ecule of N,N-dimethyl-acetamide (DMAC). The DMAC mol-ecules are linked to TA by strong O-H⋯O hydrogen bonds.

In the title adduct, 2C(18)H(14)N(4)·C(8)H(6)O(4), the centrosymmetric 1,4-benzene-dicarboxylic acid mol-ecule makes two O-H⋯·N hydrogen bonds to adjacent 10,11,12,13-tetra-hydro-4,5,9,14-tetra-azadibenzo[a,c]anthracene (TTBT) mol-ecules. Aromatic π-π stacking inter-actions occur between TTBT rings [centroid-centroid distance = 3.570 (3) Å], leading to a two-dimensional supra-molecular structur...
