Crystal structure and Hirshfeld surface analysis of (E)-N-[(2-ethoxynaphthalen-1-yl)methylidene]-5,6,7,8-tetrahydronapntnalen-1-amine

Abstract

In the title Schiff base compound, C23H23NO, the two ring systems are twisted by 51.40 (11)degrees relative to each other. In the crystal, the molecules are connected by weak C-H center dot center dot center dot pi interactions, generating a three-dimensional supramolecular structure. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H center dot center dot center dot H (67.2%), C center dot center dot center dot H/H center dot center dot center dot C (26.7%) and C center dot center dot center dot C (2.5%) interactions.
