چکیده
The mol-ecule of the title compound, C(10)H(9)NO(5), is approximately planar, with the mean planes of the nitro, carboxyl and all-yloxy groups rotated by 8.1 (3), 7.9 (3) and 4.52 (18)°, respectively, from the plane of the benzene ring. Bond lengths in the aromatic ring are influenced by both electronic effects and strain induced by ortho-substitution. In the crystal structure, centrosymmetrically related mol-ecules are paired into dimers through strong O-H⋯O hydrogen bonds.

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).

The title compound, C(10)H(8)N(2)·2C(7)H(5)NO(4),was obtained unintentionally as the harvested product of the hydro-thermal reaction between Co(OAc)(2)·4H(2)O and 4,4'-bipyridine in the presence of 3-nitro-phthalic acid. In the reaction, 3-nitro-phthalic acid is transformed into 3-nitro-benzoic acid by an in situ deca-rboxylation reaction, in which the carboxyl-ate group is not deprotonated and...

In the title compound, C(7)H(6)N(2)O(4), an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds then link the dimers, generating R(3) (3)(16)R(2) (1)(6) motifs. The whole mol-ecule is essentially planar, with the greatest deviation from the ...

The asymmetric unit of the title compound, C(14)H(16)N(4) (2+)·2C(7)H(4)NO(4) (-)·2C(7)H(5)NO(4), comprises one-half of the 3,3'-(p-phenyl-enedimethyl-ene)di-1H-imidazol-1-ium dication, which lies on an inversion centre, one 4-nitro-benzoate anion and one 4-nitro-benzoic acid mol-ecule. In the crystal, the components are linked into a two-dimensional network parallel to (110) by O-H⋯O, N-H⋯O an...
