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
Abstract
The backbone of the title molecule, C26H25BrN4O, 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 (10overline{2}) occur, with the molecules interacting via weak C—H...N(cyano) and C—H...Br bonds and short N(cyano)...Br contacts [3.345 (4) Å].
