The mol-ecular conformation of the title compound, C(20)H(17)N(3), is stabilized by an intramolecular C-H⋯N inter-action. The crystal structure shows inter-molecular C-H⋯π inter-actions. The dihedral angle between the isoquinoline unit and the phenyl ring is 11.42 (1)° whereas the isoquinoline unit and the pendent dimethyl pryrazole unit form a dihedral… (More)
The asymmetric unit of the title compound, C(16)H(12)O(3), contains two crystallographically independent mol-ecules. The isochromene ring system is planar (maximum deviation 0.024 Å) and is oriented at dihedral angles of 2.63 (3) and 0.79 (3)° with respect to the methoxy-benzene rings in the two independent mol-ecules.
In the title compound, C(23)H(15)ClFNOS, the isoquinoline system and the 4-chloro-3-fluoro-phenyl ring are aligned at 80.4 (1)°. The dihedral angle between the isoquinoline system and the pendant (unsubstituted) phenyl ring is 19.91 (1)°.
In the title moleclue, C(19)H(21)NO, the 4-piperidone ring adopts a chair conformation in which the two benzene rings and the methyl group attached to C atoms all have equatorial orientations. In the crystal structure, centrosymmetric dimers are formed through weak inter-molecular C-H⋯O hydrogen bonds [the dihedral angle between the aromatic rings is 58.51… (More)
In the title compound, C(19)H(16)ClNO(2), the dihedral angle between the plane of the phenyl substituent and 3-acetyl-quinoline unit is 75.44 (5)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
The title compound, C(4)H(5)N(3)O(2), features an essentially planar mol-ecule (r.m.s. deviation for all non-H atoms = 0.013 Å). The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions (centroid-centroid distance 3.882 Å).
In the title compound, C(5)H(7)N(3)O(2), all non-H atoms lie in a common plane, with a maximum deviation of 0.061 (2)° for the ester methyl C atom. The structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
