Ammonium 4-(4-carb-oxy-phen-oxy)benzoate.

ABSTRACT: The anions of the title salt, NH(4) (+)·HO(2)CC(6)H(4)-O-C(6)H(4)CO(2) (-), are linked by inter-molecular -CO(2)H?O(2)C- hydrogen bonds, forming a polyanionic chain in the crystal; adjacent chains are connected through the ammonium cation into a layer structure, with the ammonium cation serving as hydrogen-bond donor to four carboxyl-ate O atoms. The cation and anion both lie on special positions of 2 site symmetry. In the anion, the rings make a dihedral angle of 65.3?(1)°. The acid H atom is disordered about the special position.

Dimethyl-ammonium 3-carb-oxy-benzoate.

Project description:The asymmetric unit of the title organic salt, C(2)H(8)N(+)·C(8)H(5)O(4) (-), consists of two dimethyl-ammonium cations and two 3-carb-oxy-benzoate anions. The 3-carb-oxy-benzoate anions are linked via strong inter-molecular and nearly symmetrical O-H?O hydrogen bonds forming infinite chains parallel to [111]. Neighbouring chains are further connected by the dimethyl-ammonium cations via N-H?O bonds, resulting in a double-chain-like structure. The dihedral angles of all carboxylate groups with respect to the phenylene rings are in the range 7.9?(1)-20.48?(9)°.

Dieth-yl(hy-droxy)ammonium 3-carb-oxy-benzoate.

Project description:In the title molecular compound, C(4)H(12)NO(+)·C(8)H(5)O(4) (-), the N,N-dieth-yl(hy-droxy)ammonium cation (DTHA) is linked to the 3-carb-oxy-benzoate anion (HBDL) by O-H⋯O and N-H⋯O hydrogen bonds with a graph-set motif R(2) (2)(7). In the crystal, helical chains are formed by O-H⋯O hydrogen bonds, propagating along [010]. The crystal structure is further stabilized by π-π inter-actions between inversion-related HBDL benzene rings [centroid-centroid distance = 3.900 (4) Å] and C-H⋯O inter-actions.

4-Carb-oxy-pyridin-1-ium 2,4,5-tri-carb-oxy-benzoate monohydrate.

Project description:The title hydrated salt, C6H6NO2 (+)·C10H5O8 (-)·H2O, was isolated from the 1:1 cocrystallization of benzene-1,2,4,5-tetra-carb-oxy-lic acid and isonicotinic acid in ethanol solution. In the crystal, the cation is close to planar [r.m.s. deviation = 0.085?Å for the nine fitted atoms; the C-C-C-O(carbon-yl) torsion angle = -8.7?(4)°], but twists are evident in the anion, with all but the carb-oxy-lic acid group diagonally opposite the carboxyl-ate group being significantly twisted out of the plane of the benzene ring [C-C-C-O(carbon-yl) torsion angles = -118.1?(2), -157.6?(2), 4.3?(3) and 77.3?(3)°]. In the crystal, the ions and water mol-ecules are consolidated into a three-dimensional architecture by O-H?O and N-H?O hydrogen bonding along with C-H?O inter-actions.

Project description:In the crystal of the title mol-ecular salt, C(5)H(8)N(3) (+)·C(8)H(5)O(4) (-), the diamino-pyridine cation and the phthalate anion are linked by a pair of N-H⋯O hydrogen bonds. Within the phthalate anion, an almost symmetrical O-H⋯O hydrogen bond is observed. The ion pairs are linked by further N-H⋯O hydrogen bonds, generating a two-dimensional network lying parallel to (10).

2-Phen-oxy-ethyl benzoate.

Project description:In the title compound, C15H14O3, the dihedral angle between the benzene rings is 75.85?(7)°. In the crystal, centrosymmetrically related mol-ecules are weakly associated through pairs of inter-actions between a benzene ring and an O atom of the ester group [ring centroid?O = 3.952?(7)?Å], and through pairs of inter-actions between the other benzene ring and an O atom of the phen-oxy group [ring centroid?O = 3.912?(7)?Å], giving chains extending along [110].

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).

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].
