Anomeric effect and hydrogen‐bonded supramolecular motif in 5‐(3‐fluoro‐4‐methoxyphenyl)‐1‐[(3‐fluoro‐4‐methoxyphenyl)aminomethyl]‐1,3,5‐triazinane‐2‐thione

In the title compound, C₁₈H₂₀F₂N₄O₂S, the triazinane‐2‐thione ring adopts an envelope conformation, the ring substituents lie on the same side of the mean plane of the heterocyclic ring and the exo lp—N—C—N_triaz unit (lp is a lone pair and triaz is the triazinane ring) exhibits an antiperiplanar orientation, which is shown to be governed by strong anomeric effects. Molecules are linked into a complex three‐dimensional framework by a combination of two N—H...S hydrogen bonds, three C—H...F hydrogen bonds and a π–π stacking interaction.
