4-Chloro-anilinium 3-carb-oxy-prop-2-enoate.

ABSTRACT: In the title compound, C(6)H(7)ClN(+)·C(4)H(3)O(4) (-), the cations and anions lie on mirror planes and hence only half of the mol-ecules are present in the asymmeric unit. The 4-chloro-anilinium cation and hydrogen maleate anion in the asymmetric unit are each planar and are oriented at an angle of 15.6 (1)° to one another and perpendicular to the b axis. A characterestic intra-molecular O-H⋯O hydrogen bond, forming an S(7) motif, is observed in the maleate anion. In the crystal, the cations and anions are linked by N-H⋯O hydrogen bonds, forming layers in the ab plane. The aromatic rings of the cations are sandwiched between hydrogen-bonded chains and rings formed through the amine group of the cation and maleate anions, leading to alternate hydro-phobic (z = 0 or 1) and hydro-philic layers (z = 1/2) along the c axis.

2-Amino-5-chloro-pyridinium (Z)-3-carb-oxy-prop-2-enoate 0.25-hydrate.

Project description:In the title hydrated salt, C(5)H(6)ClN(2) (+)·C(4)H(3)O(4) (-)·0.25H(2)O, the water O atom lies on a twofold axis with 0.25 occupancy. The 2-amino-5-chloro-pyridinium cation is almost planar, with a maximum deviation of 0.015 (3) Å. In the hydrogen malate anion, an intra-molecular O-H⋯O hydrogen bond generates an S(7) ring and results in a folded conformation. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming layers parallel to the ab plane which stack down the c axis.

4-Meth-oxy-anilinium 2-carb-oxy-4,5-di-chloro-benzoate.

Project description: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 carboxyl O-atom acceptors together with cation-anion ?-? ring inter-actions [minimum ring centroid separation = 3.734?(3)?Å] give rise to a sheet structure lying parallel to (001).

Project description: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.

Between the sheets there are weak π-π associations between alternating cation-anion aromatic ring systems [shortest centroid-centroid separation = 3.735 (4) Å].

These planes are further interconnected by O-H?O interactions into a three-dimensional network.
