2-(1-Methyl-2-oxoindolin-3-ylidene)malononitrile
The title mol-ecule, C12H7N3O, is almost planar, with an r.m.s. deviation of 0.026 Å. No directional interactions could be detected in the crystal.
متن کاملMethyl 2-acetamido-2-(1-acetyl-3-hydroxy-2-oxoindolin-3-yl)propanoate
In the title isatin compound, C(16)H(18)N(2)O(6), the pyrrolidine ring adopts an envelope conformation and is inclined at a dihedral angle of 7.31 (5)° with respect to the benzene ring. The acetyl group is disordered over two positions with refined occupancies of 0.503 (4) and 0.497 (4). These groups make dihedral angles of 12.6 (6) and 19.6 (7)° with the pyrrolidine ring. In the crystal struct...
متن کامل4-Methyl-N′-(2-oxoindolin-3-ylidene)benzene-1-sulfonohydrazide
In the title compound, C(15)H(13)N(3)O(3)S, the C-S-N(H)-N linkage is non-planar, the torsion angle being -65.12 (13)° and the S atom showing a tetra-hedral environment. The compound has two almost planar fragments linked to the S atom: the isatin-derivative fragment [(C(8)H(5)NO)N-N(H)-] and the tolyl fragment [C(7)H(7)-] have maximum deviations from the mean plane through the non-H atoms of 0...
متن کاملCrystal structure of methyl (E)-2-(1-methyl-2-oxoindolin-3-ylidene)acetate
The title compound, C12H11NO3, is essentially planar, with the mean plane of the acetate side chain [-C-C(=O)-O-C] being inclined to the mean plane of the indole ring system by 12.49 (7)°. The five- and six-membered rings of the indole group are almost coplanar, making a dihedral angle of 1.76 (8)°. The conformation about the C=C bond is E and there is an intra-molecular C-H⋯O hydrogen bond pre...
متن کامل(Z)-2-(5-Methyl-2-oxoindolin-3-ylidene)-N-phenylhydrazinecarbothioamide
In the title compound, C(16)H(14)N(4)OS, the dihedral angle between the nine-membered 5-methyl-indolin-2-one ring system and the benzene ring is 10.21 (7)°. Intra-molecular cyclic N-H⋯O and C-H⋯S hydrogen-bonding inter-actions [graph set S(6)] are present within the N-N-C-N chain between the ring systems. In the crystal, mol-ecules form centrosymmetric cyclic dimers through pairs of N-H⋯O hydro...
