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

ABSTRACT: 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).

4-Chloro-anilinium 2-carb-oxy-4,5-dichloro-benzoate.

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. 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 ?-? associations between alternating cation-anion aromatic ring systems [shortest centroid-centroid separation = 3.735?(4)?Å].

Isopropyl-aminium 2-carb-oxy-4,5-di-chloro-benzoate.

Project description:In the structure of the 1:1 proton-transfer compound of isopropyl-amine with 4,5-dichloro-phthalic acid, C(3)H(10)N(+)·C(8)H(3)Cl(2)O(4) (-), the three cation H-atom donors associate with three separate carboxyl O-atom anion acceptors, giving conjoint cyclic R(4) (4)(12), R(4) (4)(16) hydrogen-bonding cation-anion inter-actions in a one-dimensional ribbon structure. In the anions, the carboxyl groups lie slightly out of the plane of the benzene ring [maximum deviations = 0.439?(1) for a carboxylic acid O atom and 0.433?(1)?Å for a carboxyl-ate O atom]. However, the syn-related proton of the carboxylic acid group forms the common short intra-molecular O-H?O(carbox-yl) hydrogen bond.

Methyl 2-amino-4,5-di-meth-oxy-benzoate.

Project description:The title compound, C10H13NO4, is essentially planar, with an r.m.s. deviation of 0.049?Å. An intra-molecular C-H?O hydrogen bond occurs and the amino group forms an intra-molecular N-H?Oester hydrogen bond; the other H atom forms an inter-molecular N-H?Ocarbon-yl hydrogen bond, leading to the formation of a helical chain that runs along the b-axis direction.

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

Project description: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.

The anions are essentially planar "[maximum deviation 0.214?(1)?Å (a carboxyl O)] with the syn-related H atom of the carboxyl group, forming a short intra-molecular O-H?O(carbox-yl) hydrogen bond.

4-Methyl-pyridinium 2-carb-oxy-4,5-dichloro-benzoate monohydrate.

Project description:In the structure of the 1:1 proton-transfer compound of 4-methyl-pyridine (?-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.
