چکیده
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.

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].

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.

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 π-π 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...
