Abstract: In the title molecule, C48H42N4O5, a potential non-linear optical compound, the furan ring [r.m.s. deviation = 0.010 (1) Å] and the indolylidene ring system [r.m.s. deviation = 0.013 (2) Å] are inclined to one another by 18.52 (6)°. This is similar to the arrangement [16.51 (18)°] found for the N-hydroxyethyl adduct of the title compound [Bhuiyan et al. (2011). Mol. Cryst. Liq. Cryst. 548, 1-12]. Replacing the hydroxyethyl group with 3,5-dibenzyloxybenzoate has not resulted in a non-centrosymmetric lattice arrangement or significant changes to the basic molecular structure. In the crystal, molecules are linked via pairs of C-HN hydrogen bonds, forming inversion dimers with an R22(20) ring motif. The dimers are linked via C-HO hydrogen bonds, forming C(17) chains along . The chains are linked by further C-HN hydrogen bonds, forming layers parallel to (001) and enclosing R22(44) ring motifs. There are also C-H interactions present, stabilizing the interlayer orientation of the pendant bis(benzyloxy)benzoyloxy group.
