(E)-3-(2,3,4,5,6-Penta-fluoro-styr-yl)thio-phene.

ABSTRACT: The reaction of thio-phene-3-carboxaldehyde and perfluoro-benzyl-triphenyl-phospho-nium bromide in the presence of sodium hydride gave the title compound, C(12)H(5)F(5)S, in 70% yield. The thiophene and perfluorophenyl groups form a dihedral angle of 5.4 (2)°. The structure is characterized by a head-to-tail organization in a columnar arrangement due to π-π inter-actions between the thio-phene and penta-fluoro-phenyl rings with centroid-centroid distances in the range 3.698 (2)-3.802 (2) Å.

1-[(2,3,4,5,6-Penta-fluoro-phen-yl)ethyn-yl]ferrocene.

Project description:The mol-ecular structure of the title compound, [Fe(C(5)H(5))(C(13)H(4)F(5))], consists of a ferrocenyl group and a 2,3,4,5,6-penta-fluoro-benzene group linked through an ethyne spacer. The crystal packing is dominated by inter-molecular C-H⋯F hydrogen bonds, C-F⋯π inter-actions between the penta-fluoro-benzene groups [F⋯centroid distances = 3.882 (2) and 3.884 (2) Å] and π-π inter-actions between the penta-fluoro-benzene and cyclo-penta-dienyl rings [centroid-centroid distance = 3.741 (1) Å].

1,10-Phenanthrolinium 2,3,4,5,6-penta-fluoro-benzoate-2,3,4,5,6-penta-fluoro-benzoic acid (1/2).

Project description:In the title compound, C(12)H(9)N(2) (+)·C(7)F(5)O(2) (-)·2C(7)HF(5)O(2), the cation and anion are linked by an N-H⋯O hydrogen bond. The neutral mol-ecules bond to the anion via O-H⋯O hydrogen bonds to form associations of one cation, one anion and two neutral mol-ecules.

Project description:The title compound, C(8)H(2)F(5)N(3)S, was synthesized by the reaction of perfluoro-benzoic acid and thio-semicarbazide. The dihedral angle between the thia-diazole and perfluoro-phenyl ring is 35.41 (6)°. In the crystal, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules, forming a three-dimensional network.

2,3,4,5,6-Penta-fluoro-trans-cinnamic acid.

Project description:The title compound, C9H3F5O2, crystallizes as O-H⋯O hydrogen-bonded carb-oxy-lic acid dimers that, together with C-H⋯F inter-actions and O⋯F [2.8065 (13) and 2.9628 (13) Å] and F⋯F [2.6665 (11), 2.7049 (12) and 2.7314 (12) Å] contacts, form a sheet-like structure. The sheets are stacked via short π-π inter-actions [centroid-centroid distance = 4.3198 (11) Å]. An intra-molecular C-H⋯F inter-action is also observed.

N-Benzyl-2,3,4,5,6-penta-fluoro-benz-amide.

Project description:In the title compound, C(14)H(8)F(5)NO, the dihedral angle between the planes of the penta-fluoro-phenyl and phenyl rings is 18.34 (5)°. An inter-molecular N-H⋯O hydrogen bond between the amide groups connects these mol-ecules to form an infinite chain through the crystal structure. One weak intermolecular C-H⋯O contact and one π-π interaction [centroid-centroid distance = 3.772 (3) Å] are also involved in crystal structure stabilization between the phenyl rings.

(E)-1,3-Bis(2,3,4,5,6-penta-fluoro-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(15)H(2)F(10)O, the two perfluorinated arene rings are tilted at an angle of 66.08 (5)° with respect to each other. The olefinic double bond adopts an E configuration and the single bond between the olefinic and carbonyl double bonds has an s-trans conformation. The carbonyl group is not in a coplanar alignment with respect to the neighbouring arene ring (0.963 Å from aryl plane) while being coplanar with regard to the olefinic double bond (0.0805 Å from olefinic bond). The crystal packing does not feature significant hydrogen-bond-type or stacking inter-actions.

N,N,N,N-Tetra-kis(2,3,4,5,6-penta-fluoro-benzo-yl)pyridine-2,6-diamine.

Project description:The title compound, C(33)H(3)F(20)N(3)O(4), is a highly fluorinated organic imide that was isolated as an unexpected product from the reaction of 2,6-diamino-pyridine with 2,3,4,5,6-penta-fluoro-benzoyl chloride in a 1:2 molar ratio. The mol-ecule is located on a twofold axis and one of its symmetry-independent 2,3,4,5,6-penta-fluoro-benzoyl groups is disordered over two sets of sites, the occupancy of the major component being 0.773 (3). In the major component, the dihedral angle between the perfluoro-phenyl groups is 63.64 (10)°, and these groups form dihedral angles of 67.14 (7) and 21.1 (2)° with the pyridine core. Short inter-molecular C-H⋯O and C-H⋯N contacts are found in the crystal structure.
