Crystal structure, Hirshfeld surface analysis and computational studies of 5-[(prop-2-en-1-yl)sulfanyl]-1-[2-(trifluoromethyl)phenyl]-1H-tetrazole

Abstract

The title compound, C11H9F3N4S, was synthesized from 2-(trifluoromethyl)aniline by a multi-step reaction. It crystallizes in the non-centrosymmetric space group Pna21, with one molecule in the asymmetric unit, and is constructed from a pair of aromatic rings [2-(trifluoromethyl)phenyl and tetrazole], which are twisted by 76.8 (1)° relative to each other because of significant steric hindrance of the trifluoromethyl group at the ortho position of the benzene ring. In the crystal, very weak C—H...N and C—H...F hydrogen bonds and aromatic π–π stacking interactions link the molecules into a three-dimensional network. To further analyse the intermolecular interactions, a Hirshfeld surface analysis, as well as interaction energy calculations, were performed.
