In the molecule of the title compound, C(15)H(11)NO(2), the dihedral angle between the ring systems is 81.3 (2)°. In the crystal structure, mol-ecules are held together via C-H⋯O inter-actions.

In the title compound, C(11)H(10)BrNO(2), the dihedral angle between the five- and six-membered rings of the phthalamide system is 1.00 (16)°. There are no significant inter-molecular inter-ations except for van der Waals contacts.

The title compound, C16H13NO3, exists in the keto form and the iso-quinoline system is essentially planar (mean deviation = 0.0424 Å). The dihedral angle between the aromatic rings is 4.2 (2)°. In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional structure.

The structure of the title compound, C11H7NO2, is isotypic to that of its homologue, 1-octylindoline-2,3-dione [Qachchachi et al. (2013 ▶). Acta Cryst. E69, o1801]. The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021 (1) Å for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to t...

In the title compound, C(24)H(23)NO(2)Si, the dihedral angle between the planes of the phenyl rings attached to the Si atom is 80.78 (10)°. In the crystal, the mol-ecules form sheets lying perpendicular to [101] via C-H⋯O inter-actions. These sheets are stacked and linked in a three-dimensional framework by additional C-H⋯O inter-actions in the [10] direction.

In the title compound, C(10)H(6)F(3)NO(2), the isoindole ring system is planar, the maximum atomic deviation being 0.012 (2) Å. The C-C bond of the trifluoro-ethyl group is twisted with respect to the isoindole ring by a dihedral angle of 62.58 (17)°. Weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonding is present in the crystal structure.

The title N-benzyl-phthalimide derivative, C16H13NO3, consists of two planar moieties, viz. the phthalimide system (r.m.s. deviation = 0.007 Å) and the phenyl ring, which make a dihedral angle of 84.7 (6)°. The meth-oxy group is almost coplanar with the phathalimide ring, as shown by the C-C-O-C torsion angle of -171.5 (2)°. In the crystal, the mol-ecules are self-assembled via non-classical C-...

The asymmetric unit of the title compound, C(6)H(7)NO(3), contains two mol-ecules (A and B) related by a non-crystallographic twofold pseudo-axis. The mol-ecules are joined in the (AABB)(n) manner by O-H⋯O hydrogen bonds between their hy-droxy groups, thus forming C(2) chains along the a-axis direction. Neighboring mol-ecules of the same kind (A and A, or B and B) are related by inversion cente...
