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 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 (10) 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]
