(2E)-2-(Furan-2-ylmethylidene)-2,3-dihydro-1H-inden-1-one
In the title compound, C(14)H(10)O(2), the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035 Å). A twist about the single bond linking the two residues is evident [C-C-C-C torsion angle = -13.2 (5)°]. The three-dimensional architecture is stabilized by C-H⋯O (involving the trifurcated carbonyl O atom), C-H⋯π and π-π inter-actions [between the five- and six...
متن کامل(2E)-2-[(2E)-3-Phenylprop-2-en-1-ylidene]-2,3-dihydro-1H-inden-1-one
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.
متن کامل(2E)-2-(4-Bromobenzylidene)-2,3-dihydro-1H-inden-1-one
The title indan-1-one derivative, C(16)H(11)BrO, is planar, the r.m.s. deviation for all 18 non-H atoms being 0.071 Å. The configuration about the C=C bond [1.337 (5) Å] is E. In the crystal, supra-molecular layers in the ab plane are formed by C-H⋯O inter-actions, involving the bifurcated carbonyl O atom, as well as C-H⋯π inter-actions. The studied crystal was an inversion twin.
متن کامل(2E)-2-(4-Methoxybenzylidene)-2,3-dihydro-1H-inden-1-one
In the title compound, C(17)H(14)O(2), the indan-1-one system is almost planar (r.m.s. deviation = 0.007 Å) and the benzene ring is twisted out of its plane by 8.15 (6)°. The conformation about the C=C double bond [1.348 (2) Å] is E. Helical supra-molecular chains along [010] feature in the crystal packing; these are sustained by C-H⋯O hydrogen bonds and π-π inter-actions between translationall...
متن کامل(2E)-2-[(2H-1,3-Benzodioxol-5-yl)methylidene]-2,3-dihydro-1H-inden-1-one
In the title compound, C(17)H(12)O(3), each of the five-membered rings in the inden-1-one and 1,3-benzodioxole residues is almost planar (r.m.s. deviations = 0.041 and 0.033 Å, respectively). A small twist about the single bond linking the two residues is evident [the C-C-C-C torsion angle = 8.7 (4)°]. Supra-molecular zigzag layers propagating in the ac plane are formed in the crystal via C-H⋯O...
