| Abstract: | 4-(4,6-Dimethoxyl-pyrimidin-2-yl)-3-thiourea carboxylic acid ethyl ester was synthesized by the reaction of 2-amino-4,6-dimethoxyl pyrimidine,potassium thiocyanate and methyl chloroformate in ethyl acetate.Single crystals suitable for X-ray measurement were obtained by recrystallization with the solvent of dimethyl formamidc at room temperature.The crystal structure was determined by X-ray diffraction analysis.Crystallographic data:C10H14N4O4S,Mr=286.31,monoclinic,space group C2/c with a=2.5309(3),b=0.67682(6),c=1.74237(19)nm,β=114.744(3)°,V=2.7106(5)nm3,Dc=1.403 g/cm3,μ=0.225mm-1,F(000)=1200,Z=8,R=0.0514 and wR=0.1529. |
