ABSTRACT
The whole mol-ecule of the title compound, C27H26N2O2, is generated by twofold rotational symmetry, with the central C atom of the pentyl chain located on the twofold rotation axis. The compound crystallizes as a bis-zwitterion, and there are two intra-molecular N-H⋯O hydrogen bonds generating S(6) ring motifs. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming ribbons propagating along [001], and enclosing R 2 (2)(22) ring motifs.

The mol­ecular structure of the title compound, with atom labelling. Displacement ellipsoids are drawn at the 50% probability level. The intra­molecular hydrogen bonds are shown as dashed lines (see Table 1 ▸). The unlabelled atoms are related to the labelled atoms by twofold rotational symmetry (atom C14 lies on the twofold axis; symmetry code: −x, y, −z + ).

The intra­molecular hydrogen bonds are shown as dashed lines (see Table 1 ▸). The unlabelled atoms are related to the labelled atoms by twofold rotational symmetry (atom C14 lies on the twofold axis; symmetry code: −x, y, −z + ).

Mentions: The whole mol­ecule of the title compound, Fig. 1 ▸, is generated by twofold rotational symmetry, with the central C atom of the pentyl chain, C14, located on the twofold rotation axis. It crystallizes as a bis-zwitterion, with strong intra­molecular N—H⋯O hydrogen bonding between the imino N atom N1 (N1’), and the O atom, O1 (O1i) [d (O⋯N) = 2.5437 (17) Å; symmetry code: (i) −x, y, −z + ], forming S(6) ring motifs (Fig. 1 ▸ and Table 1 ▸). The pentyl chain has an extended conformation with the naphthalene rings inclined to one another by 89.94 (5)°.
