چکیده
The structure of the 1:1 proton-transfer compound of 4-chloro-aniline with 4,5-dichloro-phthalic acid (DCPA), viz. C(6)H(7)ClN(+)·C(8)H(3)Cl(2)O(4) (-), has been determined at 130 K. The non-planar hydrogen phthalate anions and the 4-chloro-anilinium cations form two-dimensional O-H⋯O and N-H⋯O hydrogen-bonded substructures which have no peripheral extension. Between the sheets there are weak π-π associations between alternating cation-anion aromatic ring systems [shortest centroid-centroid separation = 3.735 (4) Å].

In the structure of the title anhydrous salt, C(4)H(12)N(+)·C(8)H(3)Cl(2)O(4) (-), the 4,5-dichloro-phthalate monoanions have the common 'planar' conformation with the carboxyl groups close to coplanar with the benzene ring and with a short intra-molecular carb-oxy-lic acid O-H⋯O hydrogen bond. In the crystal, a two-dimensional sheet structure is formed through aminium N-H⋯O(carbox-yl) hydrogen...

The title compound, C(9)H(8)N(2)O(8), was obtained by the reaction of imidazole-4,5-dicarb-oxy-lic acid and 2-chloro-acetic acid. An intra-molecular O-H⋯O hydrogen bond occurs. The crystal packing is stabilized by intermolecular O-H⋯O and C-H⋯O hydrogen bonds, which link mol-ecules into a three-dimensional network.

In the title salt C7H10NO(+)·C8H3Cl2O4 (-) the benzene rings of the cation and anion are essentially parallel [inter-ring dihedral angle 4.8 (2)°]. In the anion the carb-oxy-lic acid and carboxyl-ate groups make dihedral angles of 19.0 (2) and 79.5 (2)°, respectively, with the benzene ring. Aminium N-H⋯O, carb-oxy-lic acid O-H⋯O and weak aromatic C-H⋯O hydrogen-bonding associations with carboxy...
