چکیده
In the structure of the 1:1 proton-transfer compound of 4-methyl-pyridine (γ-picoline) with 4,5-dichloro-phthalic acid, C(6)H(8)N(+)·C(8)H(3)Cl(2)O(4) (-)·H(2)O, determined at 200 K, the 4,5-dichloro-phthalate anions are bridged by the water mol-ecule through O-H⋯O(carbox-yl) hydrogen bonds, giving zigzag chains which extend along the c-axis direction. The 4-methyl-pyridinium cations are linked to the chains through single N-H⋯O(water) hydrogen bonds and occupy the voids within the chains in the one-dimensional structure. The anions have the common 'planar' conformation with a short intra-molecular O-H⋯O(carbox-yl) hydrogen bond.

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...

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...

In the crystal structure of the title salt, C(6)H(9)N(2) (+)·C(7)H(5)O(6)S(-)·H(2)O, the water mol-ecule acts as an acceptor of bifurcated N-H⋯O hydrogen bonds from the pyridinium H atom and one H atom of the 2-amino group, forming an R(2) (1)(6) ring. The 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions self-assemble via O-H⋯O hydrogen bonds, leading to supra-molecular chains along the a axis. T...
