N,N'-Bis(2,2,3,3,4,4,4-hepta-fluoro-butyl)naphthalene-1,4:5,8-tetra-carboximide.

ABSTRACT: The title mol-ecule, C(22)H(8)F(14)N(2)O(4), lies across a crystallographic inversion center with the naphthalene diimide core essentially planar (mean deviation from plane is 0.0583?Å). The CF(2) groups in the perfluorobutyl chains are in an energetically favorable all trans conformation. In the crystal structure, mol-ecules are packed in slightly displaced layers so that the side chains overlap the aromatic naphthalene diimide rings, thus minimizing any possible ?-? overlap.

The title mol-ecule, C(22)H(8)F(14)N(2)O(4), lies across a crystallographic inversion center with the naphthalene diimide core essentially planar (mean deviation from plane is 0.0583 Å). The CF(2) groups in the perfluorobutyl chains are in an energetically favorable all trans conformation. In the crystal structure, mol-ecules are packed in slightly displaced layers so that the side chains overlap the aromatic naphthalene diimide rings, thus minimizing any possible π-π overlap. ...[more]

Project description:The title compound, C(30)H(30)N(2)O(6), has crystallographic inversion symmetry with the nitro-gen atom and the two oxygen atoms of the naphthalene diimide system deviating by -0.243?(2), 0.109?(3) and 0.247?(2)?Å, respectively, from the plane defined by the carbon atoms.

2,3,5,6-Tetra-fluoro-1,4-bis-(trimethyl-sil-yl)benzene.

Project description:The asymmetric unit of the title compound, C(12)H(18)F(4)Si(2), contains two independent mol-ecules, both lying on inversion centers. The C(arene)-Si distances are significantly longer than in the analogous non-fluorinated compound. The packing of the mol-ecules results in a herringbone motif in the ac plane.

Crystal structure of N,N'-bis-(2,4-di-fluoro-benzo-yloxy)benzene-1,2:4,5-tetra-carboximide.

Project description:Mol-ecules of the title compound, C24H8F4N2O8, have Ci point-group symmetry in the crystal, as they lie on crystallographic inversion centres (Z' = 1/2). The di-fluoro-phenyl ring is disordered over two orientations; the final refined occupancy factors of the two components of disorder are 0.947 (4) and 0.053 (4). In the crystal, some Car-H⋯F inter-actions are present, which involve the most acidic H atom of the mol-ecule.

2,3,5,6-Tetra-fluoro-1,4-bis-(2-pyridylmethyl-eneamino-meth-yl)benzene.

Project description:The title compound, C(20)H(14)F(4)N(4), is a flexible bis-pyridine-type ligand with an extended fluorinated spacer group between the two pyridyl functions. The centroid of the central aromatic ring is situated on a crystallographic center of inversion. The dihedral angle between the pyridine ring and the central benzene ring is 63.85?(9)°. The crystal structure exhibits inter-molecular C-H?F hydrogen-bonding inter-actions.

[1,4-Phenyl-enebis(methyl-ene)]bis-(tri-phenyl-phospho-nium) bis-(tetra-fluoro-borate).

Project description:The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.329 (6) to 1.391 (6) Å] deviate significantly from their standard values.

3,3'-Dimethyl-1,1'-(butane-1,4-di-yl)diimidazolium bis-(tetra-fluoro-borate).

Project description:The title compound, C(12)H(20)N(4) (2+)·2BF(4) (-), was prepared by the anion exchange of a dibromide ionic liquid with sodium tetra-fluoro-borate. The asymmetric unit contains one half of the imidazolium cation, which lies about an inversion centre at the mid-point of the central C-C bond of the linking butyl chain. The two planar imidazole rings (r.m.s. deviation = 0.0013?Å) are strictly parallel and separated by 2.625?(7)?Å [vertical distance between the centroids of two imidazole rings], giving the mol-ecule a stepped appearance. In the crystal structure, inter-molecular C-H?F hydrogen bonds link the cations and anions, generating a three-dimensional network.

1-Butyl-quinine tetra-fluoro-borate.

Project description:In the title salt (2S,4S,8R)-1-butyl-2-[(R)-(hydr-oxy)(6-methoxy-quinolin-4-yl)meth-yl]-8-vinyl-quinuclidin-1-ium tetra-fluoro-borate, C(24)H(33)N(2)O(2) (+)·BF(4) (-), the butyl substituent at the 1-position is in an equatorial conformation with respect to the unsubstituted six-membered ring and the four butyl C atoms are almost coplanar with the ring N and vinyl C atoms (r.m.s. deviation = 0.046 Å). In the crystal, the cations are linked by O-H⋯N hydrogen bonds. The F atoms of the tetra-fluoro-borate group are disordered over two sets of site with an occupancy raitio of 0.552 (8):0.448 (8).

Poly[bis-(ethanol)(?4-2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ato)cadmium].

Project description:In the title compound, [Cd(C8F4O4)(C2H5OH)2] n , the Cd(II) cation sits on an inversion centre and is coordinated by six O atoms from four tetra-fluoro-benzene-1,4-di-carboxyl-ate anions and two ethanol mol-ecules in a distorted octa-hedral geometry. The anionic ligand is also located on an inversion centre, and connects four Cd(II) cations, generating a two-dimensional polymeric layer parallel to the ab plane. Within the layer, the ethanol mol-ecule links F and O atoms of the nearest anionic ligands via O-H?O and O-H?F hydrogen bonds. The ethyl group of the ethanol mol-ecule is disordered over two positions with an occupancy ratio of 0.567?(10):0.433?(10).
