title: 2-{2-[5-(4-Cyano-5-di-cyano-methyl-idene-2,2-dimethyl-2,5-di-hydro-furan-3-yl)penta-2,4-dienyl-idene]-3,3-dimethyl-2,3-di-hydro-1H-indol-1-yl}ethyl 3,5-bis-(benz-yloxy)benzoate.
abstract: In the title mol-ecule, C48H42N4O5, a potential non-linear optical compound, the furan ring [r.m.s. deviation = 0.010 (1) Å] and the indolyl-idene 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-hy-droxy-ethyl adduct of the title compound [Bhuiyan et al. (2011 ▶). Mol. Cryst. Liq. Cryst. 548, 1-12]. Replacing the hy-droxy-ethyl group with 3,5-di-benzyl-oxybenzoate has not resulted in a non-centrosymmetric lattice arrangement or significant changes to the basic mol-ecular structure. In the crystal, mol-ecules 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 inter-actions present, stabilizing the inter-layer orientation of the pendant bis-(benz-yloxy)benzo-yloxy group.
