Rac-1,2,3,4-Tetra-hydro-1,4-methano-anthracene-6,7-dicarbonitrile.

ABSTRACT: The title compound, C(17)H(12)N(2), comprises a norbornane unit having a dicyanona-phthalene ring fused on one side. Both cyano groups are twisted slightly out of the plane of the naphthalene ring system [C-C-C-C torsion angle = 1.9 (2)°]. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯N hydrogen bonds, forming dimers.

Project description:The title compound, C(15)H(12)Br(2), comprises a norbornane unit having a dibromo-naphthalene ring fused on one side. Both Br atoms are twisted slightly out of the plane of the naphthalene ring system with a Br-C-C-Br torsion angle of 5.3?(5)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H?Br hydrogen bonds, forming an infinite C(9) chain along [110].

6,7-Difluoro-1,2,3,4-tetra-hydro-quin-oxa-line-5,8-dicarbonitrile.

Project description:In the title compound, C10H6F2N4, the Car-N bonds are slightly shortened with respect to a standard aniline C-N bond [1.3580?(16) and 1.3618?(16) versus 1.39?Å], thus indicating some ?-? conjgation with the electron-acceptor CN groups. The mol-ecule, except for two C atom of the ethyl-ene bridge, is nearly planar, the largest deviation of the other non-H atoms from the mean plane being 0.309?(2)?Å. The N-C-C-N torsion angle involving the ethyl-ene bridge is 50.23?(18)°. In the crystal, mol-ecules are connected by pairs of N-H?N hydrogen bonds into chains along [21-1].

1,2,3,4-Tetra-hydro-1,4-methano-naphthalene-2,3-diol.

Project description:The title compound, C(11)H(12)O(2), is an inter-mediate in the synthesis of Varenicline, a nicotinic receptor partial agonist used to treat smoking addiction. In the crystal structure, there is an intra-molecular O-H⋯O hydrogen bond that generates an S(5) ring motif. Inter-molecular O-H⋯O hydrogen bonds form centrosymmetric dimers and also link these dimers into chains along the a axis.

(1R,4S)-7,8-Dichloro-1,2,3,4-tetra-hydro-1,11,11-trimethyl-1,4-methano-phenazine.

Project description:The title compound, C(16)H(16)Cl(2)N(2), was synthesized by the condensation reaction between 4,5-dichloro-o-phenyl-ene-diamine and (1R)-(-)-camphorquinone in boiling acetic acid. The two crystallographically independent mol-ecules in the unit cell are related by a pseudo-inversion center.

rac-2-Methyl-3,4,5,6-tetra-hydro-2H-2,6-methano-1,3-benzoxazocin-4-one.

Project description:The title compound, C(12)H(13)NO(2), represents a conformationally restricted 2-pyridone analogue of 1,4-dihydro-pyridine-type calcium antagonists and was selected for a crystal structure determination in order to explore some aspects of drug-receptor inter-action. In the mol-ecule, two stereogenic centres are of opposite chirality, whereas a racemate occurs in the crystal. It was found that the formally aminic N atom of the heterocycle is essentially sp(2)-hybridized with the lone-pair electrons partially delocalized through conjugation with the adjacent carbonyl bond. As a result, the central pyridone ring assumes an unsymmetrical half-chair conformation. The critical 4-phenyl ring is fixed in a pseudo-axial and perpendicular orientation [dihedral angle 85.8?(1)°] with respect to the pyridone ring via an oxygen bridge. In the crystal a pair of centrosymmetric N-H?O hydrogen bonds connect mol-ecules of opposite chirality into a dimer. The dimers are packed by hydrophobic van der Waals inter-actions.

Ortho-rhom-bic polymorph of (6,7-dimeth-oxy-1,2,3,4-tetra-hydro-isoquinolin-1-yl)methanol.

Project description:The asymmetric unit of the title compound, C(12)H(17)NO(3), contains two mol-ecules with different conformations. It is a polymorph of the monoclinic form [El Antri et al. (2004 ?). Mol-ecules, 9, 650-657]; the samples were crystallized at different temperatures from the same solvent. In both structures, mol-ecules are linked by O-H?N hydrogen bonds, forming chains. The conformations of the chains and their packing differ markedly in the two polymorphs.

(1,4,7,10,13,16-Hexaoxa-cyclo-octa-decane-?(6) O)bis-(tetra-hydro-furan-?O)potassium bis-[(1,2,3,4-?)-anthracene]cobalt(-I) tetra-hydro-furan monosolvate.

Project description:The asymmetric unit of the title compound, [K(C12H24O6)(C4H8O)2][Co(C14H10)2]·C4H8O, consists of one cationic potassium complex, one anionic cobalt dianthracene complex and one tetra-hydro-furan solvent mol-ecule. The potassium cation is situated at the centre of an 18-crown-6 mol-ecule and between two tetra-hydro-furan mol-ecules, the latter coordin-ating above and below the mean plane formed by the O atoms of the crown ether mol-ecule. The Co atom is coordinated by eight C atoms of two anthracene mol-ecules in an ?(4) manner. The third free tetra-hydro-furan mol-ecule shows orientational disorder on two partially occupied positions [occupancy ratio 0.561?(8):0.439?(8)].

[(1R,3S)-6,7-Dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinolin-3-yl]methanol 2.33-hydrate.

Project description:The title compound, C(18)H(21)NO(3)·2.33H(2)O, is the fourth reported member in a series of (1R,3S)-6,7-dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinoline derivatives used in catalysis as ligands (or their precursors). The N-heterocycle in the structure adopts a half-chair conformation. The dihedral angle between the benzene rings is 77.29?(13)°. There are three ill-resolved water molecules of crystallization in the structure (one of them rotationally disordered about a threefold axis) involved in short contacts probably due to hydrogen bonding.
