1,4-Bis(4,5-dihydro-1H-imidazol-2-yl)benzene–terephthalic acid–water (1/1/4)

The asymmetric unit of the title compound, C12H14N4·C8H6O4·4H2O, consists of one half of the 1,4-bis­(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) mol­ecule, one half of the terephthalic acid (TA) mol­ecule and two water mol­ecules. Both the bib and the TA mol­ecules reside on crystallographic inversion centers, which coincide with the centroids of the respective benzene rings. The bib and the TA, together with the water mol­ecules, are linked through inter­molecular O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds, forming a three-dimensional network of stacked layers. Weak inter­molecular C—H⋯O contacts support the stability of the crystal structure.
