5-Amino-4-bromo-2,3-dihydro-1H-inden-1-one
In the title compound, C(9)H(8)BrNO, the non-H-atom framework is essentially planar, with a maximum deviation of 0.087 (3) Å. In the crystal, mol-ecules are inter-connected into a three-dimensional network by C-H⋯O and N-H⋯O hydrogen bonds. In addition, C-H⋯π inter-actions and a π-π stacking inter-action, with a centroid-centroid distance of 3.5535 (19) Å, are also observed.

The title compound, C(13)H(9)BrO, has been synthesized by the intra-molecular Friedel-Crafts reaction of 1-(1-bromo-4-naphth-yl)-3-chloro-propan-1-one. There are two approximately planar [maximum deviations of 0.8 (2) and 0.4 (2) Å in the two mol-ecules] molecules in the asymmetric unit. The dihedral angle between their mean planes is 19.72 (8)°. Weak inter-molecular C-H⋯O hydrogen bonding is p...
متن کامل(E)-2-[4-(Piperidin-1-yl)benzylidene]-2,3-dihydro-1H-inden-1-one
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...
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...
متن کامل(E)-5,6-Dimethoxy-2-(pyridin-4-ylmethylidene)-2,3-dihydro-1H-inden-1-one
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.
