چکیده
In the title adduct, C(7)H(5)NO(4)·0.5C(6)H(6)N(4), the complete biimidazole molecule is generated by a crystallographic inversion centre. In the crystal, N-H⋯O and O-H⋯N hydrogen bonds connects the 4-nitro-benzoic acid and 2,2'-biimidazole units, affording multi-dimensional frameworks with graph-set descriptor R(2) (2)(9).

In the title compound, C(6)H(6)N(4)·2C(7)H(6)O(2), the asymmetric unit contains a half-mol-ecule of biimidazole and one benzoic acid mol-ecule. The unit cell contains two biimidazole mol-ecules and four benzoic acid mol-ecules, giving the reported 2:1 ratio of benzoic acid to biimidazole. The biimidazole mol-ecule is located on an inversion center (passing through the central C-C bond). Strong ...
