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

Abstract: The mol­ecules in (E)-N-(3,4,5-tri­meth­oxy­benzyl­idene)naph­thalen-1-amine, C20H19NO3, (I), and its reduction product N-(3,4,5-tri­meth­oxy­benzyl)naphthalen-1-amine, C20H21NO3, (II), are both conformationally chiral, but (I) crystallizes in a centrosymmetric space group, while (II) crystallizes with just one conformational enantio­mer in each crystal. A combination of two C-H...O hydrogen bonds links the mol­ecules of (I) into sheets containing a single type of R66(44) ring, and these sheets are linked into a continuous three-dimensional array by a single [pi]-[pi] stacking inter­action. The mol­ecules of (II) are linked into complex sheets by a combination of N-H...O, C-H...O and C-H...[pi](arene) hydrogen bonds.

Formula: C20H19NO3 and C20H21NO3

Keywords: crystal structure; supra­molecular structure; hydrogen bonding.
