The article examines the synthesis of imidazolidine-2-thiones. The study shows that the bond lengths and bond and torsion angles in molecule II approach the corresponding standard values. Compounds I-III in crystal have thione structure and that tautomeric equilibrium between the thione and thiol tautomers is possible in solution. The positions of hydrogen atoms were determined from the difference synthesis and were refined in anisotropic approximation. |
