    (3aR,4S,7R,7aS)-2-Phenyl-4-propyl-3a,4,7,7a-tetrahydro-1H-4,7-epithioisoindole-1,3-dione 8-oxide
    (WILEY-BLACKWELL, 2011) Demircan, Aydin; Sahin, Ertan; Beyazova, Gozde; Karaaslan, Muhsin; Hokelek, Tuncer
    In the tetrahydroisoindole moiety of the title compound, C17H17NO3S, the six-membered ring assumes a boat configuration and the -S=O group bridges the prow and stern of the boat. The phenyl ring is oriented at a dihedral angle of 83.2 (1)degrees with respect to the pyrrole ring. In the crystal, intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. A weak C-H center dot center dot center dot pi interaction involving the phenyl ring is also found. The crystal studied was an inversion twin.

    4-methoxy-2-[(E)-(phenylimino)methyl]phenol
    (INT UNION CRYSTALLOGRAPHY, 2008) Ucan, Selma; Ozturk, Asli; Sarikavakli, Nursabah; Hokelek, Tuncer
    In the molecule of the title compound, C14H13NO2, the two aromatic rings are oriented at a dihedral angle of 0.78 (20)degrees; with the exception of two methyl H atoms the molecule is essentially planar. The intramolecular O-H center dot center dot center dot N hydrogen bond results in the formation of a non-planar, six-membered ring, which adopts a flattened-boat conformation. In the crystal structure, intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules to form parallel networks. There is a C-H center dot center dot center dot pi contact between the methyl group and the benzene ring. A pi-pi contact between the benzene and phenyl rings [centroid-centroid distance = 4.681 (5) angstrom] is also observed.
