9,10-Dioxoanthracene-1,4-diyl bis-(4-methyl-benzene-sulfonate).

ABSTRACT: The title mol-ecule, C(28)H(20)O(8)S(2), has a T-shaped conformation. The central 9,10-anthraquinone moiety is bow-shaped with the two outer aromatic rings being inclined to one another by 13.99?(11)°. The benzenesulfonate rings are inclined to one another by 47.35?(12)°, and by 34.51?(11) and 17.88?(11)° to the bridging aromatic ring of the 9,10-anthraquinone moiety. In the crystal, C-H?O interactions link the mol-ecules into ribbons in [100].

Tri-cyclo-[3.3.1.0(3,7)]nonane-3,7-diyl bis-(4-methyl-benzene-sulfonate).

Project description:The title compound, C23H26O6S2 was synthesized by esterification of tri-cyclo-[3.3.1.0(3,7)]nonane-3,7-diol with p-toluene-sulfonyl chloride. The mol-ecule has symmetry 2 and is situated on site 4e. The C-C bond length between the quartenary C atoms is 1.598?(2)?Å, which is considerably longer than other C-C bonds in the mol-ecule. There are C-H?O inter-actions present in the structure. As a consequence, the packing of the molecule (viewed along [100]) appears as chains where the molecules run parallel, but each chain has the opposite direction to the neighboring ones.

9,10-Dioxo-9,10-di-hydro-anthracene-1,4-diyl di-acetate.

Project description:In the title compound, C18H12O6, the anthra-quinone ring system is nearly planar [maximum deviation = 0.161?(3)?Å] and both acetate groups are located on the same side of the ring plane. A supra-molecular architecture arises in the crystal owing to ?-? stacking between parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.883?(4)?Å] and weak inter-molecular C-H?O hydrogen bonding.

Project description:In the title mol-ecular salt, [Mg(H(2)O)(6)](C(7)H(8)NO(3)S)(2), the Mg(2+) cation lies on an inversion centre. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds, thereby generating sheets parallel to (001).

Crystal structure of piperazine-1,4-diium bis-(4-amino-benzene-sulfonate).

Project description:The asymmetric unit of the title salt, C4H12N2 (2+)·2C6H6NO3S(-), consists of half a piperazindiium dication, located about an inversion centre, and a 4-amino-benzene-sulfonate anion. The piperazine ring adopts a chair conformation. In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework. Within the framework there are C-H⋯π inter-actions and the N-H⋯O hydrogen bonds result in the formation of R 4 (4)(22) and R 3 (4)(13) ring motifs.

Bis[(E)-1-methyl-4-styrylpyridinium] 4-chloro-benzene-sulfonate iodide.

Project description:In the title compound, 2C(14)H(14)N(+)·C(6)H(4)ClO(3)S(-)·I(-), each cation exists in an E configuration with respect to the ethenyl bond. The dihedral angle between the pyridinium and benzene rings is 3.98?(6)° in one of the cations and 9.88?(7)° in the other. The two cations are arranged in an anti-parallel manner with ?-? inter-actions between pyridinium and benzene rings [centroid-centroid distance = 3.5805?(8)?Å]. The benzene ring of the anion makes dihedral angles of 61.20?(6) and 64.25?(6)° with the pyridinium rings of the two cations. In the crystal, the cations are stacked in an anti-parallel manner along the a axis, while the anions are linked into chains along the same direction. The ions are linked into a three-dimensional network by C-H?I and C-H?O hydrogen bonds and C-H?? inter-actions. The crystal under investigation was an inversion twin, with a ratio of 61.7?(5):38.3?(5) for the two components.

Project description:In the title compound, 2C(14)H(14)N(+)·C(6)H(4)BrO(3)S(-)·I(-), two crystallographically independent cations exist in an E configuration with respect to the C=C ethenyl bond.

Redetermination of ethyl-ene-diammonium bis-(p-methyl-benzene-sulfonate) monohydrate.

Project description:In the asymmetric unit of the title compound, C(2)H(10)N(2) (2+)·2C(7)H(7)O(3)S(-)·H(2)O, there are two independent 4-methyl-benzene-sulfonate anions, one ethyl-enediammonium cation and a water mol-ecule. The present redetermination was carried out to improve the treatment of disorder, which was not refined in the previous study [Ahn & Kim (1985 ▶). J. Korean Chem. Soc.29, 335-340]. One of the sulfonate groups is disordered over two positions, with site-occupancy factors of 0.588 (14) and 0.412 (14). Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds hold the three components together, affording a layer structure extending parallel to the (001) plane.
