(2E)-2-Benzylidene-5,6-dimethoxyindan-1-one
The mol-ecular structure of the title compound, C(18)H(16)O(3), is roughly planar; the maximum deviation of the indanone ring system is 0.027 (1) Å and it makes a dihedral angle of 2.69 (3)° with the phenyl ring. The torsion angles between the two meth-oxy groups and the -indanone ring are -14.67 (11) and -1.11 (12)°. In the crystal, mol-ecules are connected into a ribbon along the a axis via w...

The title indan-1-one derivative, C(18)H(14)O, is planar with an r.m.s. deviation for all 19 non-H atoms of 0.098 Å. The conformation about each of the C=C bonds [1.343 (3) and 1.349 (3) Å] is E. Supra-molecular layers in the bc plane, mediated by C-H⋯O and π-π [ring centroid-centroid distance = 3.5282 (15) Å] inter-actions, feature in the crystal packing.

In the title compound, C(15)H(11)ClO, the dihedral angle between the mean planes of the benzene ring and the chloro-substituted benzene ring is 48.8 (3)°. The dihedral angles between the mean plane of the prop-2-ene-1-one group and the mean planes of the 3-chloro-phenyl and benzene rings are 27.0 (4) and 27.9 (3)°, respectively. In the crystal, weak inter-molecular C-H⋯π-ring inter-actions occur.

In the title compound, C(15)H(12)OS, the cyclo-hexene ring has a twisted boat conformation with the C atom between the ketone and methyl-ene atom and this methyl-ene C atom lying 0.280 (3) and 0.760 (3) Å, respectively, from the plane through the remaining four atoms (r.m.s. deviation = 0.004 Å). The dihedral angle between the benzene and thio-phene rings [21.64 (9)°] indicates an overall twist...

In the title compound, C26H19NO, the plane of the aromatic heterocycle makes a dihedral angle of 75.22 (4)° with that of the attached phenyl ring. In the crystal, mol-ecules are connected by C-H⋯O inter-actions, generating R 2 (2)(12) dimers. These dimers are further connected by C-H⋯π inter-actions, linking the mol-ecules into chains running along the a-axis direction.
