1,3-Difluoro-benzene.

ABSTRACT: The weak electrostatic and dispersive forces between C(?+)-F(?-) and H(?+)-C(?-) are at the borderline of the hydrogen-bond phenomenon and are poorly directional and further deformed in the presence of other dominant inter-actions, e.g. C-H??. The title compound, C(6)H(4)F(2), Z' = 2, forms one-dimensional tapes along two homodromic C-H?F hydrogen bonds. The one-dimensional tapes are connected into corrugated two-dimensional sheets by further bi- or trifrucated C-H?F hydrogen bonds. Packing in the third dimension is controlled by C-H?? inter-actions.

The weak electrostatic and dispersive forces between C(δ+)-F(δ-) and H(δ+)-C(δ-) are at the borderline of the hydrogen-bond phenomenon and are poorly directional and further deformed in the presence of other dominant inter-actions, e.g. C-H⋯π. The title compound, C(6)H(4)F(2), Z' = 2, forms one-dimensional tapes along two homodromic C-H⋯F hydrogen bonds. The one-dimensional tapes are connected into corrugated two-dimensional sheets by further bi- or trifrucated C-H⋯F hydrogen bonds. Packing in t ...[more]

N-(3,4-Difluoro-phen-yl)-3,4-dimethoxy-benzene-sulfonamide.

Project description:In the title sulfonamide derivative, C(14)H(13)F(2)NO(4)S, the dihedral angle between the benzene rings is 66.05 (9)°. The crystal structure is stabilized by weak inter-molecular N-H⋯O hydrogen bonds involving the amine and meth-oxy groups, which link the mol-ecules into a one-dimensional chain. No significant inter-chain contacts are observed.

2-Iodo-1,3-dimethoxy-benzene.

Project description:Crystals of the title compound, C(8)H(9)IO(2), were obtained from a dimethyl sulfoxide solution of 2,6-dimethoxy-benzoic acid and iodo-benzene diacetate under a nitro-gen atmosphere at 353?K. In the crystal structure, mol-ecules are linked by weak C-H?? inter-actions, generating inter-penetrating one-dimensional chains of perpendicularly oriented mol-ecules extending along [011] and [01]. Chains are also formed through non-bonding C-I?? contacts extending in the same directions, projecting a zigzag motif in view down [100]. The I?Cg distance is 3.695?(2)?Å and the C-I?Cg angle is 164.17?(14)°. The mol-ecular symmetry m coincides with the mirror plane of the space group Cmc2(1), resulting in a half-mol-ecule in the asymmetric unit (Z' = ½).

2,5-Dimethyl-1,3-dinitro-benzene.

Project description:The title compound, C(8)H(8)N(2)O(4), was prepared via the nitration of p-xylene. The mol-ecules are stacked along the c axis in an antiparallel manner. The two nitro groups are rotated relative to the benzene ring with dihedral angles of 44.50 (7) and 31.67 (8)°. The tilt of the nitro groups allows the formation of C-H⋯O inter-actions between the ring C-H and nitro groups of adjacent mol-ecules creating puckered sheets perpendicular to the c axis. The H atoms of the methyl group in the 5-position are disordered (60° rotation) with an occupancy of 0.616 (19) for the major component. The crystal was found to be a non-merohedral twin with a twin law [-1 -0.002 0.005, 0.00031 -1 0.002, 0.118 -0.007 1] corresponding to a rotation of 180° about the reciprocal axis (001) and refined to give a minor component fraction of 0.320 (2).

4,6-Dinitro-benzene-1,3-diamine.

Project description:The mol-ecule of the title compound, C(6)H(6)N(4)O(4), is almost planar, being stabilized by two intra-molecular N-H⋯O hydrogen bonds. Further N-H⋯O links lead to a sheet in the crystal structure.

4,4'-Difluoro-2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol.

Project description:In the title compound, C(17)H(18)F(2)N(2)O(2), the imidazolidine ring system exists in a twist conformation. The mean plane through this ring system forms dihedral angles of 80.8?(8)° and 66.2?(13)°, with the benzene rings. The dihedral angle between the benzene rings is 52.0?(14)°. Two intra-molecular O-H?N hydrogen bonds each generate S(6) ring motifs. In the crystal, weak C-H?O hydrogen bonds form dimers, which are connected by further C-H?O inter-actions.

5-Bromo-benzene-1,3-dicarbo-nitrile.

Project description:The asymmetric unit of the title compound, C8H3BrN2, consists of two mol-ecules. The crystal structure features undulating mol-ecular sheets with the mol-ecules linked by C-H?N hydrogen bonds with one N atom acting as a bifurcated acceptor. N?Br inter-actions also occur [N?Br = 2.991?(3) and 3.099?(3)?Å]. Inter-layer association is accomplished by offset face-to-face arene inter-actions [centroid-centroid distance = 3.768?(4)?Å].

1,3-Bis(phenyl-sufanylmeth-yl)benzene.

Project description:The complete mol-ecule of the title compound, C(20)H(18)S(2), is generated by crystallographic mirror symmetry, with two C atoms lying on the mirror plane. All of the independent atoms are contained within two planes defined by the thio-phenyl rings (C(6)S) and the central phenyl ring with the methyl-ene bridge; the r.m.s deviations of these planes are 0.012 and 0.025?Å, respectively. The two planes are almost perpendicular to one another at a dihedral angle of 80.24?(10)°. Inter-molecular C-H-? inter-actions are present in the crystal structure.

Project description:The title compound, C8H8Cl2, used in the synthesis of many pharmaceutical inter-mediates, forms a three-dimensional network through chlorine-chlorine inter-actions in the solid-state that measure 3.513 (1) and 3.768 (3) Å.

N-(5-Chloro-1,3-thia-zol-2-yl)-2,4-difluoro-benzamide.

Project description:The title compound, C(10)H(5)ClF(2)N(2)OS, was obtained by linking an amino heterocycle and a substituted benzoyl chloride. The dihedral angle between the two rings is 41.2?(2)° and the equalization of the amide C-N bond lengths reveals the existence of conjugation between the benzene ring and the thia-zole unit. In the crystal, pairs of N-H?N hydrogen bonds link mol-ecules into inversion dimers. Non-classical C-H?F and C-H?O hydrogen bonds stabilize the crystal structure.
