1-(1-Decyl-2-oxoindolin-3-ylidene)thiosemicarbazide
In the title 1-alkylisatin 3-thiosemicarbazone, C19H28N4OS, the imine C=N bond has a Z configuration, whereas the N—N—C=S unit has an E conformation. In the crystal, molecules are connected by N—H⋯O hydrogen bonds, forming zigzag chains running along the b axis
3-Hydroxy-4-phenyl-1-(prop-2-en-1-yl)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one
The asymmetric unit of the title compound, C18H18N2O2, contains three independent molecules. In each, the seven-membered diazepine ring adopts a boat conformation with the hydroxy-substituted C atom at the prow and fused-ring C atoms at the stern. In the crystal, the molecules are linked by O—H⋯O and N—H⋯O hydrogen bonds. The allyl group of one molecule is equally disordered over two positions
5,5′′-Dibromo-1,1′′-bis(prop-2-en-1-yl)-1,1′′,2,2′′-tetrahydrodispiro[indole-3,7′-[6,9]diazatricyclo[7.3.0.02,6]dodecane-8′,3′′-indole]-2,2′′-dione
In the molecule of the title compound, C30H30Br2N4O2, the piperazine ring adopts a chair conformation. The pyrrolidine rings that are fused to the piperazine ring adopt envelope conformations (in which the N atom represents the flap). The indoline fused-ring systems are nearly planar (r.m.s. deviations = 0.009 and 0.019 Å); the two fused rings are aligned at 60.63 (6)°
1,1′-Dibenzyl-5,5′′-dichloro-1,1′′,2,2′′-tetrahydrodispiro[indole-3,7′-[6,9]diazatricyclo[7.3.0.02,6]dodecane-8′,3′′-indole]-2,2′′-dione
In the title compound, C38H34Cl2N4O2, the piperazine ring adopts a chair conformation. The pyrrolidine rings that are fused to the piperazine ring adopt envelope conformations (in which the C atoms connecting the two rings represent the flap). The indoline ring systems are approximately planar (r.m.s. deviations = 0.026 and 0.034 Å) and are aligned at a dihedral angle of 54.98 (3)°
1-Tetradecylindoline-2,3-dione
In the title N-alkyl isatin, C22H33NO2, the isatin moiety is planar (r.m.s. deviation = 0.03 Å). The tetradecyl substituent has all torsion angles in an antiperiplanar conformation
1-(1-Nonyl-2-oxoindolin-3-ylidene)thiosemicarbazide
In the title compound, C18H26N4OS, the imine C=N bond has a Z configuration, whereas the N—N—C=S unit has an E conformation. In the crystal, molecules are connected through N—H⋯O hydrogen bonds, forming zigzag chains running along the b axis. The nonyl chain adopts an extended zigzag conformation
1-Decylindoline-2,3-dione
In the title N-alkyl isatin, C18H25NO2, 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
