摘要
The title compounds of 3-aryl-5-cyano-6-methylthiopyrimidine2.4-diones weresynthesized by the reaction of ethy1 2-cyano-3.3'dimethylthioacrylate with arylureas. The compound(Ar＝p-CH_3OC_6H_4) was recrystallized in acetone/petroleum in space group P2_(1/n) with a＝1. 1602 (2).b=1.5921(3), c＝1.3918 (3)um. β=94.38 (3)°for Z=8. R=0.054.The X-ray analysis showedthat there is H-bond interaction among molecules.
