AbstractThe title compound, C29H28N4O2, excluding the hydroxyethyl and methyl groups, is slightly twisted from planarity so that the terminating indol-2-yl-idene and furan-2-yl-idene moiety planes subtend a dihedral angle of 6.27 (8)°. A small inwards fold in the polymethine atom chain is consistent with centrosymmetric dimer formation via O - H⋯N(cyano) hydrogen bonds. In the crystal, the mol-ecules pack in layers approximately parallel to the (101̄) plane via pairs of O - H⋯N and C - H⋯N(cyano) inter-actions. © Gainsford et al. 2011.
