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 ...
The title compound, C(25)H(18)N(4)O, is a non-planar bipolar ligand containing triphenyl-amine and 1,3,4-oxadiazole units. In the mol-ecule, the benzene ring, the 1,3,4-oxadiazole ring, and the pyridine ring are twisted slightly with respect to each other [dihedral angle between the benzene and 1,3,4-oxadiazole rings = 9.4 (4) and between the 1,3,4-oxadiazole and pyridine rings = 3.0 (4)°]. Mor...
In the title pyrimidine derivative, C12H16N2OS, the tetra-hydro-pyrimidine ring adopts an envelope conformation with the C atom of the methyl-ene -CH2- group as the flap. In the crystal, N-H⋯O and N-H⋯S hydrogen bonds connect mol-ecules into undulating sheets perpendicular to the a axis.
