The crystal and molecular structures of the cycloadduct from isopropyl[α‐(dimethylthio‐carbamoyl)isopropyl]carbodiimide and methyl isothiocyanate were determined by single‐crystal X‐ray methods. The product was established to be 2‐(1‐isopropyl‐3,5‐dimethyl‐4,6‐dithioxo‐hexahydro‐1,3,5‐triazine‐2‐ylidenamino)‐ N,N ‐dimethylthioisoburyramide, in which contrary to expectations based on hybridisation the heterocyclic ring adopts a boat conformation.
