2-[(E)-2-(4-Chloro-phen-yl)ethen-yl]-1-methyl-pyridinium 4-chloro-benzene-sulfonate.

ABSTRACT: In the title salt, C(14)H(13)ClN(+)·C(6)H(4)ClO(3)S(-), the cation exists in an E configuration with respect to the ethynyl bond and is approximately planar, with a dihedral angle of 3.4?(2)° between the pyridinium and benzene rings. The anion is approximately perpendicular to the cation plane, the benzene ring of the anion making dihedral angles of 89.4?(2) and 89.9?(2)°, respectively, with the pyridinium and benzene rings of the cation. In the crystal structure, the cations are linked into a chain along the c axis by C-H?Cl inter-actions. The anions are linked to the adjacent cation chains by C-H?O and C-H?Cl inter-actions, forming a two-dimensional network parallel to the bc plane. The crystal structure is further stabilized by C-H?? inter-actions. A ?-? inter-action is also observed between the pyridinium ring and the benzene ring of the cation with a centroid-centroid distance of 3.668?(3)?Å.

Project description:In the asymmetric unit of the title salt, C(14)H(13)ClN(+)·C(7)H(7)O(4)S(-), there are two crystallographically independent mol-ecules for each component. Each cation adopts an E configuration with respect to the C=C bond and is slightly twisted; the dihedral angle between the pyridinium and benzene rings is 6.53?(7)° for one mol-ecule and 5.30?(7)° for the other. The meth-oxy groups in the anion mol-ecules are each twisted from the mean plane of benzene ring with torsion angles of 16.38?(19) and 4.32?(19)°. In the crystal structure, the cations are stacked in an anti-parallel manner along the a axis and the anions are linked together by C-H?O inter-actions into a layer parallel to (001). The anion layers are further linked to adjacent cations by C-H?O inter-actions. C-H?? inter-actions involving the benzene rings of both ions are also observed.

Project description:In the title compound, C(14)H(13)ClN(+)·C(6)H(4)BrO(3)S(-), the cation exists in an E configuration with respect to the ethenyl bond and is almost planar, the dihedral angle between the pyridinium and the benzene rings being 2.80 (7)°. The dihedral angles between the benzene ring of the anion and the pyridinium and benzene rings of the cation are 80.88 (7) and 79.05 (7)°, respectively. In the crystal, the cations are stacked into columns along the a axis as a result of π-π inter-actions between the pyridinium and chloro-benzene rings with a Cg⋯Cg distance of 3.6976 (8) Å. The anions are linked into chains along the a axis by weak C-H⋯O inter-actions. These anion chains are linked to adjacent cations by additional weak C-H⋯O and C-H⋯Br inter-actions, forming a two-dimensional network parallel to the ab plane. There are also short O⋯Br [3.2567 (11) Å] and C⋯O [2.9917 (18) Å] contacts. The crystal structure is further stabilized by C-H⋯π inter-actions involving the aromatic ring of the anion.

Project description:In the title compound, C(12)H(12)NS(+)·C(6)H(4)ClO(3)S(-), the cation is almost planar and exists in the E configuration. The cations and anions form alternate layers parallel to the ab plane. Within each layer, both cations and anions form chains directed along the b axis.

The sulfonate and thio-phene groups are involved in weak intra-molecular C-H?O and C-H?S inter-actions, respectively. The latter intra-molecular hydrogen bonds produce S(5) ring motifs.
