The three-dimensional structure of some 4,5-dihydro-1,3,5-dithiazine derivatives was investigated by means of dipole moments and the Kerr effect. The presence of equilibrium boat and chair forms in the conformational mixture is proposed for the 2,4,6-trimethyl and 2,4,-5, 6-tetramethyl derivatives. Energy data that confirm the possibility of anomalous conformations are presented. © 1974 Consultants Bureau.
