Terephthalic acid-2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole (2/3).

In the crystal structure of the title compound, 2C(8)H(6)O(4)·3C(20)H(22)N(4), there are three independent 2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole mol-ecules, each of which lies on an inversion centre. The terephthalic acid mol-ecules are linked to adjacent 2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole mol-ecules via O-H⋯N hydrogen bonds.
