H. Jiang and X.-W. Dong

Abstract: In the crystal structure of the title compound, 2C₈H₆O₄·3C₂₀H₂₂N₄, there are three independent 2,2'-dimethyl-1,1'-(butane-1,4-diyl)dibenzimidazole molecules, each of which lies on an inversion centre. The terephthalic acid molecules are linked to adjacent 2,2'-dimethyl-1,1'-(butane-1,4-diyl)dibenzimidazole molecules via O-HN hydrogen bonds.
