Crystal structure of 1,13,14-triazadibenz[a,j]anthracene 1,1,2,2-tetrachloroethane monosolvate

The asymmetric unit of the title compound, C19H11N3·C2H2Cl4, consists of one half-molecule of 1,13,14-triazadibenz[a,j]anthracene (dibenzo[c,h]-1.9,10-anthyridine, dbanth) and one half of 1,1,2,2-tetrachloroethane (TCE), both of which are located on a crystallographic twofold rotation axis. The dihedral angle between the planes of the terminal benzene rings in dbanth is 3.59 (7)° owing to the steric repulsion between the H atoms in the two benzo groups and the H atom in the central pyridine ring of the anthridine skeleton. In the crystal, π–π interactions between pyridine rings [centroid–centroid distances = 3.568 (2) and 3.594 (2) Å] link the dbanth molecules to form a one-dimensional columnar structure along the c axis. The dbanth and TCE molecules are connected through weak bifurcated C—H...(N,N) hydrogen bonds
