10,11,12,13-Tetrahydro-4,5,9,14-tetra-azadibenz[a,c]anthracene-benzene-1,4-dicarboxylic acid (2/1).


ABSTRACT: 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 ?-? stacking inter-actions occur between TTBT rings [centroid-centroid distance = 3.570?(3)?Å], leading to a two-dimensional supra-molecular structure in the crystal.

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 structure in the crystal. ...[more]
