2-{2-[5-(4-Cyano-5-di­cyano­methyl­idene-2,2-dimethyl-2,5-di­hydro­furan-3-yl)penta-2,4-dienyl­idene]-3,3-dimethyl-2,3-di­hydro-1H-indol-1-yl}ethyl 3,5-bis­(benz­yloxy)benzoate

In the title mol­ecule, C(48)H(42)N(4)O(5), 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—H⋯N hydrogen bonds, forming inversion dimers with an R (2) (2)(20) ring motif. The dimers are linked via C—H⋯O hydrogen bonds, forming C(17) chains along [010]. The chains are linked by further C—H⋯N hydrogen bonds, forming layers parallel to (001) and enclosing R (2) (2)(44) ring motifs. There are also C—H⋯π inter­actions present, stabilizing the inter­layer orientation of the pendant bis­(benz­yloxy)benzo­yloxy group.
