Crystal structure and Hirshfeld surface analysis of N,N '-bis(3-tert-butyl-2-hydroxy-5-methylbenzylidene)ethane-1,2-diamine

Abstract

The title compound, C26H36N2O2, crystallizes in the phenol-imine form. In the molecule, there are intramolecular O-H center dot center dot center dot N hydrogen bonds forming S(6) ring motifs, and the two aromatic rings are inclined to each other by 37.9 (7)degrees. In the crystal, molecules are linked by pairs of weak C-H center dot center dot center dot O hydrogen bonds, forming inversion dimers. 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 (77.5%), H center dot center dot center dot C/C center dot center dot center dot H (16%), H center dot center dot center dot O/O center dot center dot center dot H (3.1%) and H center dot center dot center dot N/N center dot center dot center dot H (1.7%) interactions.
