5-Chloroindoline-2,3-dione
The title compound, C(8)H(4)ClNO(2), is almost planar (r.m.s. deviation for the non-H atoms = 0.023 Å). In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into C(4) chains propagating in [001] and C-H⋯O inter-actions cross-link the chains.
متن کامل3,8-Dimethylacenaphthylene-1,2-dione
In the title compound, C(14)H(10)O(2), the acenaphthene-quinone core is essentially planar, with an r.m.s. deviation of 0.0140 Å. In the crystal, mol-ecules are connected by π-π stacking inter-actions [centroid-centroid distances = 3.766 (3), 3.839 (3) and 3.857 (3) Å], forming columns parallel to the a axis.
متن کامل1-Decylindoline-2,3-dione
In the title N-alkyl isatin, C(18)H(25)NO(2), the isatin moiety is almost planar (r.m.s. deviation = 0.03 Å). C-C-C-C torsion angles of the decyl substituent indicate an all-antiperiplanar conformation.
متن کاملPyrrolidine-2,5-dione
In the title compound, C(4)H(5)NO(2), the non-H atoms are nearly coplanar, with a maximum deviation of 0.030 (1) Å. In the crystal, pairs of mol-ecules are linked by N-H⋯O hydrogen bonds into inversion dimers.
متن کامل1,4-Dibromobutane-2,3-dione
The asymmetric unit of the title compound, C(4)H(4)Br(2)O(2), contains one half-mol-ecule, being located about a centre of inversion. In the crystal, there are no significant inter-molecular inter-actions.
