3-Benzyl-5-butyl-1,3,5-thia-diazinane-2-thione
Abstract:
In the title compound, C(14)H(20)N(2)S(2), the 1,3,5-thia-diazinane-2-thione ring adopts an envelope conformation. The S=C bond length is 1.6776 (15) Å, whereas the S-C bond lengths are 1.7470 (15) and 1.8479 (17) Å. The intramolecular C-H⋯S hydrogen bond between the thione and the benzyl units along with the C-H⋯π interaction between the butyl group and the centroid of the benzene ring may be effective in stabilizing the molecule.
