چکیده
The title compound, C(16)H(14)N(2)OS(2), is an example of a push-pull butadiene in which the electron-releasing and electron-withdrawing attachments on either end of the butadiene chain enhance the conjugation in the system. The mol-ecules are linked by inter-molecular C-H⋯N inter-actions.

The title compound, C(13)H(14)N(2)OS(2)·H(2)O, appears in the form of bimolecular aggregate in which mol-ecular components are linked by O-H⋯N hydrogen bonding. The nine-membered imidazo[1,2-a]pyridine system is almost planar, with a mean deviation of 0.026 (1) Å. An intra-molecular C-H⋯O hydrogen bond forms within the imidazo[1,2-a]pyridine system. The crystal packing is consolidated by O-H⋯O ...

In the title compound, C11H11NO3S2, the S-Csp (2) bonds are shorter [1.746 (3) and 1.750 (2) Å] than the S-CH3 bonds [1.794 (3) and 1.806 (3) Å], which we attribute to d-π inter-actions between the S atoms and the C=C bond. The 1,1-bis-(methyl-sulfan-yl)-3-oxo-propyl-ene fragment and the 4-nitro-phenyl group are both almost planar, with the largest deviations from their mean planes being 0.053 ...

The backbone of the title mol-ecule, C(26)H(25)BrN(4)O, is approximately planar: the dihedral angle between the planes of the indoline ring system and the furan ring is 7.68 (14)°. In the crystal, layers lying parallel to (10) occur, with the mol-ecules inter-acting via weak C-H⋯N(cyano) and C-H⋯Br bonds and short N(cyano)⋯Br contacts [3.345 (4) Å].
