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

Abstract

In the crystal structure of the title compound, 2C8H6O4·3C20H22N4, 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.
