Crystal structure of 4-[(5-methyl-isoxazol-3-yl)amino-sulfon-yl]anilinium 3,5-di-nitro-salicylate.

ABSTRACT: The title mol-ecular salt, C10H12N3O3S(+)·C7H3N2O7 (-), protonation occurs at the amino N atom attached to the benzene ring of sulfamethoxazole. In the anion, there is an intra-molecular O-H?O hydrogen bond and the cation is linked to the anion by an N-H?O hydrogen bond. In the extended structure, the cations and anions are linked via N-H?O, N-H?N and C-H?O hydrogen bonds, forming a three-dimensional framework.

Crystal structure of 2,5-di-methyl-anilinium salicylate.

Project description:The title mol-ecular salt, C8H12N(+)·C7H5O3 (-) arose from the proton-transfer reaction between 2,5-xylidine and salicylic acid. In the anion, the dihedral angle between the planes of the aromatic ring and the -CO2 (-) group is 11.08 (8)°; this near planarity is consolidated by an intra-molecular O-H⋯O hydrogen bond. In the crystal, the components are connected by N-H⋯O hydrogen bonds, with all three O atoms in the anion acting as acceptors; the result is a [100] chain. The structure also features weak C-H⋯O bonds and aromatic π-π stacking [centroid-to-centroid distance = 3.7416 (10) Å] inter-actions, which lead to a three-dimensional network.

Crystal structures of 4-chloro-phenyl N-(3,5-di-nitro-phen-yl)carbamate and phenyl N-(3,5-di-nitro-phen-yl)carbamate.

Project description:The title compounds, C13H8ClN3O6, (I), and C13H9N3O6, (II), differ in the orientation of the two aromatic rings. In (I), they are essentially coplanar, making a dihedral angle of 8.2 (1)°, while in (II), they are inclined to one another by 76.2 (1)°. The two nitro groups are essentially coplanar with the attached benzene rings, as indicated by the dihedral angles of 1.4 (2) and 2.3 (2)° in (I), and 4.96 (18) and 5.4 (2)° in (II). The carbamate group is twisted slightly from the attached benzene ring, with a C-N-C-O torsion angle of -170.17 (15)° for (I) and 168.91 (13)° for (II). In the crystals of of both compounds, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains propagating along [010]. In (I), C-H⋯O hydrogen bonds also link mol-ecules within the chains. The crystal packing in (I) also features a very weak π-π inter-action [centroid-centroid distance = 3.7519 (9) Å].

Project description:The crystal structures of three isomeric compounds of formula C14H13Cl2NO2S, namely 3,5-di-chloro-N-(2,3-di-methyl-phen-yl)-benzene-sulfonamide (I), 3,5-di-chloro-N-(2,6-di-methyl-phen-yl)benzene-sulfonamide (II) and 3,5-di-chloro-N-(3,5-di-methyl-phen-yl)benzene-sulfonamide (III) are described. The mol-ecules of all the three compounds are U-shaped with the two aromatic rings inclined at 41.3 (6)° in (I), 42.1 (2)° in (II) and 54.4 (3)° in (III). The mol-ecular conformation of (II) is stabilized by intra-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions. The crystal structure of (I) features N-H⋯O hydrogen-bonded R22(8) loops inter-connected via C(7) chains of C-H⋯O inter-actions, forming a three-dimensional architecture. The structure also features π-π inter-actions [Cg⋯Cg = 3.6970 (14) Å]. In (II), N-H⋯O hydrogen-bonded R22(8) loops are inter-connected via π-π inter-actions [inter-centroid distance = 3.606 (3) Å] to form a one-dimensional architecture running parallel to the a axis. In (III), adjacent C(4) chains of N-H⋯O hydrogen-bonded mol-ecules running parallel to [010] are connected via C-H⋯π inter-actions, forming sheets parallel to the ab plane. Neighbouring sheets are linked via offset π-π inter-actions [inter-centroid distance = 3.8303 (16) Å] to form a three-dimensional architecture.

Crystal structure of 3,5-di-methyl-phenyl 2-nitro-benzene-sulfonate.

Project description:The title compound, C14H13NO5S, was synthesized via a nucleophilic substitution reaction between 3,5-di-methyl-phenol and 2-nitro-benzene-sulfonyl chloride. The aromatic rings attached to the SO3 group are oriented in a gauche fashion around the ester S-O bond, with a C-S-O-C torsion angle of 84.68 (11)°. The mol-ecules form centrosymmetric dimers via π-π stacking inter-actions between 3,5-di-methyl-phenyl groups (centroid-centroid distance = 3.709 Å). An inter-molecular S=O⋯N inter-action between the sulfonyl and nitro groups, with an O⋯N distance of 2.9840 (18) Å, organizes the dimers into columns extending along [011]. These columns are further assembled into (111) layers through C-H⋯O inter-actions.

Isostructural rubidium and caesium 4-(3,5-di-nitro-pyrazol-4-yl)-3,5-di-nitro-pyrazolates: crystal engineering with polynitro energetic species.

Project description:In the structures of the title salts, poly[[μ4-4-(3,5-di-nitro-pyrazol-4-yl)-3,5-di-nitro-pyrazol-1-ido]rubidium], [Rb(C6HN8O8)] n , (1), and its isostructural caesium analogue [Cs(C6HN8O8) n , (2), two independent cations M1 and M2 (M = Rb, Cs) are situated on a crystallographic twofold axis and on a center of inversion, respectively. Mutual inter-molecular hydrogen bonding between the conjugate 3,5-dinito-pyrazole NH-donor and 3,5-di-nitro-pyrazole N-acceptor sites of the anions [N⋯N = 2.785 (2) Å for (1) and 2.832 (3) Å for (2)] governs the self-assembly of the translation-related anions in a predictable fashion. Such one-component modular construction of the organic subtopology supports the utility of the crystal-engineering approach towards designing the structures of polynitro energetic materials. The anionic chains are further linked by multiple ion-dipole inter-actions involving the 12-coordinate cations bonded to two pyrazole N-atoms [Rb-N = 3.1285 (16), 3.2261 (16) Å; Cs-N = 3.369 (2), 3.401 (2) Å] and all of the eight nitro O-atoms [Rb-O = 2.8543 (15)-3.6985 (16) Å; Cs-O = 3.071 (2)-3.811 (2) Å]. The resulting ionic networks follow the CsCl topological archetype, with either metal or organic ions residing in an environment of eight counter-ions. Weak lone pair-π-hole inter-actions [pyrazole-N atoms to NO2 groups; N⋯N = 2.990 (3)-3.198 (3) Å] are also relevant to the packing. The Hirshfeld surfaces and percentage two-dimensional fingerprint plots for (1) and (2) are described.

Crystal structures of 1-benzene-sulfon-yl-2-methyl-3-(4-nitro-benzoyl)-2,3-di-hydro-1<i>H</i>-indole and 1-benzene-sulfon-yl-2-methyl-3-[(thio-phen-2-yl)carbon-yl]-2,3-di-hydro-1<i>H</i>-indole.

Project description:In the title indole derivatives, C22H16N2O5S, (I) and C20H15NO3S2, (II), the sulfonyl-bound phenyl rings are almost orthogonal to the indole ring system, subtending dihedral angles of 88.33 (10) and 87.58 (16)°, respectively. In both compounds, the sulfonyl S atom has a distorted tetra-hedral geometry [O-S-O = 119.98 (9) and N-S-C = 104.01 (8)° for compound (I) and O-S-O = 120.08 (18) and N-S-C = 104.91 (14)° for compound (II)] and the sum of the bond angles at N indicates sp2 hybridization. The mol-ecules of both (I) and (II) feature intra-molecular C-H⋯O hydrogen bonds that generate S(6) ring motifs with the sulfone O atom. In the crystals, mol-ecules of (I) are linked by C-H-O hydrogen bonds, forming R44(18) ring motifs while mol-ecules of (II) are linked by C-H-O and C-H-S hydrogen bonds, forming R22(12) ring motifs. Compound (II) was refined as an inversion twin.

Crystal structure of ebastinium 3,5-di-nitro-benzoate.

Project description:Ebastine, 4-(benzhydr-yloxy)-1-[4-(4-tert-butyl-phen-yl)-4-oxobut-yl]piperidine, reacts with 3,5-di-nitro-benzoic acid in methanol solution to give the title 1:1 salt, ebastinium 3,5-di-nitro-benzoate, C32H40NO2+·C7H3N2O6-. In the cation, the disubstituted aryl ring exhibits orientational disorder over two sets of atomic sites having occupancies 0.706 (4) and 0.294 (6), with a dihedral angle of 41.2 (5)° between the two orientations: the bulky Ph2CH-O- substituent occupies an axial site on the piperidine ring. The two ions in the selected asymmetric unit are linked by a nearly linear N-H⋯O hydrogen bond and this, in combination with two C-H⋯O hydrogen bonds, links the ions into complex sheets.
