Crystal structure of trans-1,4-bis-[(tri-methyl-sil-yl)-oxy]cyclo-hexa-2,5-diene-1,4-dicarbo-nitrile.

ABSTRACT: The asymmetric unit of the title compound, C14H22N2O2Si2, contains one half of the mol-ecule, which is completed by inversion symmetry. The cyclo-hexa-2,5-diene ring is exactly planar and reflects the bond-length distribution of a pair of located double bonds [1.3224?(14)?Å] and two pairs of single bonds [1.5121?(13) and 1.5073?(14)?Å]. The tetra-hedral angle between the sp (3)-C atom and the two neighbouring sp (2)-C atoms in the cyclo-hexa-2,5-diene ring is enlarged by about 3°.

The asymmetric unit of the title compound, C14H22N2O2Si2, contains one half of the mol-ecule, which is completed by inversion symmetry. The cyclo-hexa-2,5-diene ring is exactly planar and reflects the bond-length distribution of a pair of located double bonds [1.3224 (14) Å] and two pairs of single bonds [1.5121 (13) and 1.5073 (14) Å]. The tetra-hedral angle between the sp (3)-C atom and the two neighbouring sp (2)-C atoms in the cyclo-hexa-2,5-diene ring is enlarged by about 3°. ...[more]

Project description:The mol-ecule of the title compound, C(12)H(14)Cl(2)O(2), lies about an inversion center. The six-membered ring is almost planar, with the largest deviation from the least-squares plane being 0.014 (4) Å. The mol-ecular conformation is stabilized by a weak intra-molecular C-H⋯O hydrogen bond.

Neighboring mol-ecules within the stack are related by the c-glide plane.

Cyclo-hexa-2,5-diene-1,4-dione-1,2,4,5-tetra-fluoro-3,6-diiodo-benzene (1/1).

Project description:The asymmetric unit of the title co-crystal adduct, C(6)H(4)O(2)·C(6)F(4)I(2), comprises a half-mol-ecule each of cyclo-hexa-2,5-diene-1,4-dione and 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene. The C(6)F(4)I(2) mol-ecule is almost planar (r.m.s. deviation = 0.0062?Å). In the crystal, the components are connected through O?I halogen bonds [3.017?(11)?Å], leading to the formation of wavelike chains along the a axis. The crystal packing also features C-H?F inter-actions.

Project description:In the structure of the title compound, C8H6Br2O4, the complete mol-ecule is generated by the application of a centre of inversion. The mol-ecule is planar (r.m.s. deviation for all non-H atoms but methyl C = 0.0358?Å), with only the methyl groups being deviated from the plane [by ±0.321?(4)?Å]. In the crystal packing, Br?O(methoxy) halogen bonds [3.2407?(19)?Å] connect molecules into supramolecular layers parallel to (101).

trans-1-Phenyl-pyrrolidine-2,5-dicarbo-nitrile.

Project description:In the title compound, C(12)H(11)N(3), the plane of the phenyl ring and the least-squares plane of the pyrrolidine ring enclose an angle of 14.30 (6)°. The intra-cyclic N atom features a nearly trigonal-planar coordination geometry due to π-inter-actions with the aromatic system. The pyrrolidine ring is present in a twist conformation for which the closest pucker descriptor is (C9)T(C8). Weak inter-molecular C-H⋯N and C-H⋯π contacts occur.

Helical supra-molecular chains along [010], mediated by C-H?N inter-actions, are found in the crystal structure.

Bis(2-{[3-methyl-4-(2,2,2-trifluoro-eth-oxy)-2-pyrid-yl]methyl-sulfan-yl}-1H,3H-benzimidazolium) 2,5-dichloro-3,6-dioxocyclo-hexa-1,4-diene-1,4-diolate.

Project description:The title salt, 2C(16)H(15)F(3)N(3)OS(+)·C(6)Cl(2)O(4) (2-), is composed of two independent cations of a lansoprazole {systematic name 2-([3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl]methylsulfinyl)-1H-benzo[d]imidazole} inter-mediate and a dianion of chloranilic acid. In the cations of the lansoprazole inter-mediate, the dihedral angles between the least-squares planes of the pyridine and benzimidazole rings are 11.1 (6) and 13.1 (5)°, respectively. The dihedral angles between the mean plane of the benzene ring in the chloranilic acid dianion and the pryidine and benzimidazole rings of the two lansoprazole inter-mediate groups are 71.8 (1)/80.5 (7) and 74.2 (4)/74.8 (6)°. In addition to ionic bond inter-actions, the lansoprazole inter-mediate and chloranilic ions are connected by strong N-H⋯O hydrogen bonds, which produce a set of extended O-H⋯O-H⋯O-H chains along the b axis in the (011) plane. In addition, weak C-H⋯O, C-H⋯F, N-H⋯Cl and π-π [centroid-centroid distances = 3.5631 (15), 3.8187 (13), 3.7434 (17) and 3.842 (2) Å] inter-molecular inter-actions are observed, which contribute to crystal packing stability.

Crystal structure of 4'-bromo-2,5-dihy-droxy-2',5'-dimeth-oxy-[1,1'-biphen-yl]-3,4-dicarbo-nitrile.

Project description:In the crystal of the title substituted hemibi-quinone derivative, C16H11BrN2O4 or [BrHBQH2(CN)2], the substituted benzene rings are rotated about the central C-C bond, forming a dihedral angle of 53.59 (7)°. The ring systems inter-act through an intra-molecular O-H⋯Ometh-oxy hydrogen bond, which induces a geometry quite different from those in previously reported hemibi-quinone structures. In the crystal, the mol-ecules associate through an inter-molecular O-H⋯Nnitrile hydrogen bond, forming chains which extend along [100] and are inter-linked through very weak C-H⋯N hydrogen bonds, giving a overall two-dimensional structure lying parallel to (010).
