2,4,6-Trifluoro-benzoic acid.

ABSTRACT: In the title compound, C(7)H(3)F(3)O(2), the C-C-C angles in the ring are greater than 120° for F-bonded C atoms [123.69?(13), 123.88?(12) and 123.66?(12)°]. In the crystal, inter-molecular O-H?O hydrogen bonds between carboxyl groups give rise to the formation of a centrosymmetric dimer, while dispersive F?O contacts [2.8849?(16)?Å] connect the dimers into infinite strands along the a axis.

In the title compound, C(7)H(3)F(3)O(2), the C-C-C angles in the ring are greater than 120° for F-bonded C atoms [123.69 (13), 123.88 (12) and 123.66 (12)°]. In the crystal, inter-molecular O-H⋯O hydrogen bonds between carboxyl groups give rise to the formation of a centrosymmetric dimer, while dispersive F⋯O contacts [2.8849 (16) Å] connect the dimers into infinite strands along the a axis. ...[more]

3-Chloro-2,4,5-trifluoro-benzoic acid.

Project description:The title compound, C7H2ClF3O2, was prepared by the chlorination of 3-amino-2,4,5-trifluoro-benzoic acid. The carboxyl group is twisted relative to the benzene ring by 6.8?(1)°. In the crystal, pairs of O-H?O hydrogen bonds link mol-ecules into typical centrosymmetric carb-oxy-lic acid dimers. These dimers are arranged into sheets parallel to (-103).

2,6-Bis(trifluoro-meth-yl)benzoic acid.

Project description:The title compound, C(9)H(4)F(6)O(2), contains two mol-ecules in the asymmetric unit, one of which exhibits disorder in both of its trifluoro-methyl groups. The dihedral angles between the benzene ring and the carboxyl group are 71.5?(2) and 99.3?(2)° in the two independent mol-ecules. The compound exhibits a catemeric structure resulting from inter-molecular O-H?O hydrogen bonding between the carboxyl groups.

2-Methyl-sulfonyl-4-(trifluoro-meth-yl)benzoic acid.

Project description:In the title mol-ecule, C(9)H(7)F(3)O(4)S, the S and the methyl C atoms of the methyl-sulfonyl group deviate from the benzene ring plane by 0.185?(2) and -1.394?(3)?Å, respectively. In the crystal, O-H?O hydrogen bonds link the mol-ecules into chains along [201]. Weak C-H?O inter-actions further link these chains into layers parallel to the ac plane.

2,4,6-Trifluoro-aniline.

Project description:The title compound, C(6)H(4)F(3)N, is a fluoro derivative of aniline. The mol-ecule shows non-crystallographic mirror symmetry. Bond lengths are normal. The C-C-C angles show some deviation from the expected ideal values by up to 5°, a finding which is in accordance with a similar structure in the literature. In the crystal structure H?F contacts and H?N contacts lead to the formation of sheets whose surfaces are made up by the hydro-phobic phenyl rings.

2-(Trifluoro-meth-yl)benzoic acid.

Project description:In the title compound, C(8)H(5)F(3)O(2), a halogenated derivative of benzoic acid, the carboxyl group is tilted by 16.8?(3)° with respect to the plane of the aromatic ring. In the crystal, O-H?O hydrogen bonding gives rise to carb-oxy-lic acid dimers, which are further connected into double chains along [1,1/4,1] by C-H?O contacts. C-H?F and C-F?? contacts are also observed.

Project description:The asymmetric unit of the title compound, C(14)H(8)ClF(3)O(3), comprises two independent mol-ecules. The rings in each molecule are connected together via O-H?O hydrogen bonds to form classical hydrogen-bonded carb-oxy-lic acid dimers. The dihedral angles between the benzene rings are 80.7?(1) and 68.7?(1)°.

Crystal structure of 2,4,6-tri-methyl-benzoic anhydride.

Project description:The title compound, C20H22O3, was formed in the reaction between 2,4,6-tri-methyl-benzoic acid and N,N-diiso-propyl-ethyl-amine in the presence of 1,3-di-chloro-1,3-bis-(di-methyl-amino)-propenium hydrogen dichloride, and was recrystallized from diethyl ether solution. It is the first exclusively alkyl-substituted benzoic anhydride to have been structurally characterized. The asymmetric unit consists of a half mol-ecule, the other half of which is generated by twofold rotation symmetry; the dihedral angle between the symmetry-related aromatic rings is 54.97?(3)°. The geometric parameters of the aromatic ring are typical of those for 2,4,6-tri-methyl-phenyl substituted groups. The C=O and C-O bond lengths are 1.1934?(12) and 1.3958?(11)?Å, respectively, and the angle between these three atoms (O=C-O) is 121.24?(9)°. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds and C-H?? inter-actions. The packing features wavy chains that extend parallel to [001].

A new polymorph of 2,6-bis-(trifluoro-meth-yl)benzoic acid.

Project description:The asymmetric unit of a second polymorph of the title compound, C(9)H(4)F(6)O(2), contains five independent mol-ecules, which form hydrogen-bonded O-H?O dimers about inversion centers. The most significant structural difference between this structure and that of the first polymorph [Tobin & Masuda (2009 ?). Acta Cryst. E65, o1217] is the hydrogen-bonded, dimeric orientation of the carb-oxy-lic acid functionalities.
