  • The synthesis and structure of 4,6-dioxopyrimido-2, 1, 3-thiadiazoles

    Syntheses and spectral indices were reported for four 4,6-dioxopyrimido-2,1,3-thiadiazoles. An x-ray diffraction structural analysis carried out using an automatic diffractometer, lambda-MoK(alpha) radiation, 1433 reflections yielded the structure of 4,6-dioxo-5,7-dimethylpyrimido-2,1,3-thiadiazole (R = 4.7%, R(w) = 5.0%). The molecule, with the exception of the methyl group hydrogen atoms, is planar. Bond delocalization is found within the heterocycles. A CNDO/2 calculation using the spd basis taking account of all the valence electrons showed that the sulfur 3d orbitals play a significant role in the formation of the S-N bonds. Anomalously short intermolecular S...O (3.033 angstrom) and C...O contacts (2.914 angstrom) were found in the crystal structure.
