1-(Morpholinomethyl)indoline-2,3-dione
In the title compound, C(13)H(14)N(2)O(3), the morpholine ring displays a chair conformation, with the (2,3-dioxoindolin-1-yl)methyl group in an equatorial position. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
متن کامل1-(Prop-2-ynyl)indoline-2,3-dione
The structure of the title compound, C11H7NO2, is isotypic to that of its homologue, 1-octylindoline-2,3-dione [Qachchachi et al. (2013 ▶). Acta Cryst. E69, o1801]. The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021 (1) Å for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to t...

In the title compound, C(16)H(12)ClNO(3), an arm-like 4-meth-oxy-benzene links to 5-chloro-indoline-2,3-dione through a methyl-ene group, with a dihedral angle between the mean planes of the benzene ring and the indole moiety of 88.44 (8)°. In the crystal, weak inter-molecular C-H⋯O and π-π stacking inter-actions [centroid-centroid distance = 3.383 (3) Å] link the mol-ecules together to form a ...
متن کامل5-Fluoro-1-(4-methoxybenzyl)indoline-2,3-dione
In the title compound, C(16)H(12)FNO(3), the dihedral angle between the benzene ring and the plane of the indole ring system is 71.60 (6)°. In the crystal, mol-ecules stack along the b axis through π-π inter-actions between the adjacent indole-2,3-dione units with a centroid-centroid distance of 3.649 (3) Å. Inter-molecular C-H⋯O=C and C-H⋯π inter-actions further stabilize the structure, formin...
