The crystal and molecular structures of the title isomeric compounds and , 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 crystallizes in space group P212121 with a=11.376(3), b=12,255(5), c=8.434(3) Å and Z=4. Crystals of , containing
晶体的标题异构体化合物的分子结构和通过分子内N,S获得-与1,2- dibro-moethane 5,5-二苯基-2-硫代海因的二烷基化,已经从X射线衍射数据来确定。2,3-二氢-6,6-二苯基咪唑基-[2,1-b]-噻唑-5(6H)-在空间群P2 1 2 1 2 1中结晶,a = 11.376(3),b = 12,255( 5),c = 8.434(3)Å,Z = 4。含一分子苯的晶体为单斜晶体,空间群P2 1 /c,a=11.539(6),b=10.242(3),c=16.353(5)Å,β= 95.45(5)°和Z = 4。在这两种情况下,都发现了两个稠合的五元杂环的平面几何形状。在所选择的键长和以及类似的咪唑并噻嗪酮和,用于计算E HOSE(谐波振荡稳定能)。还讨论了化合物对化合物的稳定性和化学反应性的问题。
