2-(4-{3-[1-(3-Bromopropyl)-3,3-dimethyl-2,3-dihydro-1H-indol-2-ylidene]prop-1-enyl}-3-cyano-5,5-dimethyl-2,5-dihydrofuran-2-ylidene)malononitrile
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].

In the title compound, C18H17FN2O, the imidazole ring makes dihedral angles of 68.81 (6) and 25.20 (8)° with the meth-oxy-phenyl and fluoro-phenyl rings, respectively. The dihedral angle between the meth-oxy-phenyl and fluoro-phenyl ring is 71.89 (6)°. In the crystal, mol-ecules are linked into inversion dimers with an R 2 (2)(8) graph-set motif by pairs of weak C-H⋯F inter-actions.

In the title compound, C(13)H(10)Cl(2)N(2)O, the ring N atom and its three attached atoms are essentially coplanar with angles adding to 359.8°, indicating conjugation with the 2-formyl-acrylonitrile subunit. The aldehyde group is oriented to place the carbonyl O atom 2.02 (3) Å from the N-H hydrogen atom. Intra-molecular N-H⋯O and C-H⋯Cl inter-actions occur. The geometry of the exocyclic doubl...

In the title compound, C(22)H(22)N(4)O(2)·0.25C(3)H(6)O, the disordered acetone mol-ecule lies with partial occupancy about the 2 axis. The mol-ecule of the malononitrile derivative is essentially planar excluding the methyl groups, with the largest deviation from the mean plane through the non-H atoms being 0.1955 (13) Å. Two rotamers with different orientations of the benzene ring are observe...
