3-Phenyltetrahydrofuran-2,5-dione
In the title compound, C(10)H(8)O(3), the dihedral angle between the approximately planar tetra-hydro-furan-2,5-dione ring [maximum deviation 0.014 (3) Å] and the phenyl ring is 85.68 (8)°. Weak C-H⋯O=C inter-molecular hydrogen-bonding contacts are observed in the structure.
متن کامل3-Methylideneoxolane-2,5-dione
The title compound (itaconic anhydride), C5H4O3, consists of a five-membered carbon-oxygen ring in a flat envelope conformation (the unsubstituted C atom being the flap) with three exocyclic double bonds to two O atoms and one C atom. In contrast to the bond lengths, which are very similar to those in itaconic acid in its pure form or in adducts with other mol-ecules, the bond angles differ sig...

In the title mol-ecule, C(9)H(8)N(2)O(2), the dihedral angle between the pyridine and the pyrrolidine rings is 64.58 (12)°. In the crystal structure, weak C-H⋯π-electron ring inter-actions stabilize the packing.
متن کامل1-(3-Chlorobenzyl)-5-iodoindoline-2,3-dione
In the title compound, C(15)H(9)ClINO(2), which possesses anticonvulsant activity, the iodo-indoline ring system is essentially planar (maximum deviation 1.245 Å) and is oriented with respect to the 3-chloro-benzyl ring at a dihedral angle of 76.59 (3)°. In the crystal, there is a π-π contact between iodo-indoline ring systems [centroid-centroid distance = 3.8188 (4) Å].
