(E)-2-(3-Chlorobenzylidene)-5,6-dimethoxy-2,3-dihydro-1H-inden-1-one
In the title compound, C(18)H(15)ClO(3), the dihydro-indenone group makes a dihedral angle of 8.56 (6)° with the bezene ring. In the crystal, the mol-ecules are inter-connected into a three-dimensional network via inter-molecular C-H⋯O hydrogen bonds. Weak C-H⋯π and π⋯π [centroid-centroid distances 3.6598 (9)-3.6913 (9) Å] inter-actions are also observed.

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(21)H(21)NO, the indene ring system is essentially planar with a maximum deviation of 0.066 (1) Å and makes dihedral angles of 7.93 (6) and 2.43 (6)°, respectively, with the benzene plane and the mean plane of the piperidine ring. These latter two planes make a dihedral angle of 7.61 (7)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, forming infinite cha...

The mol-ecule of the title compound, C(17)H(15)NO(3), is slightly twisted, with a dihedral angle of 12.12 (3)° between the dihydro-indenone group and the pyridine ring. In the crystal, mol-ecules are connected into layers parallel to the ab plane via inter-molecular C-H⋯O hydrogen bonds. Weak π-π [centroid-centroid distance = 3.5680 (6) Å] inter-actions are also observed.
متن کامل(E)-2-[4-(Trifluoromethyl)benzylidene]-2,3-dihydro-1H-inden-1-one
In the title mol-ecule, C(17)H(11)F(3)O, the indan ring system and the trifluoro-methyl-substituted benzene ring are approximately individually planar and form a dihedral angle of 1.81 (5)° with each other. In the crystal, mol-ecules are linked by pairs of weak bifurcated (C-H)(2)⋯O hydrogen bonds to form centrosymmetric dimers, generating R(2) (1)(6) and R(2) (2)(10) ring motifs. These dimers ...
