Comparison of N-(3,4,5-tri­meth­oxy­benzyl­idene)naphthalen-1-amine and its reduction product N-(3,4,5-tri­meth­oxy­benzyl)naphthalen-1-amine

N-(3,4,5-Tri­meth­oxy­benzyl­idene)naphthalen-1-amine forms simple hydrogen-bonded sheets built from C-H...O hydrogen bonds, linked by [pi]-[pi] stacking inter­actions, and its reduction product forms complex sheets built from N-H...O, C-H...O and C-H...[pi](arene) hydrogen bonds.
