The crystal and molecular structures of the title isomeric compounds 1 and 2, obtained by intramolecular N, S--dialkylation of 5, 5-diphenyl-2-thiohydantoin with 1, 2-dibro-moethane, have been determined from X-ray diffractometer data. 2, 3-Dihydro-6, 6-diphenylimidazo-[2, 1-b]-thiazol-5 (6H)-one 1 crystallizes in space group P212121 with a= 11.376 (3), b= 12,255 (5), c= 8.434 (3) Å and Z= 4. Crystals of 2, containing one molecule of benzene, are ...
