    Four compounds were prepared by reacting 4,6-dimethyl-2-mercaptopyrimidine with α-bromo-α-(1,2,4-triazol-1-yl)-substituted acetylbenzene. Their structures were identified by means of elemental analysis, IR, and 1H NMR spectra. The single crystal structure of 2- [ 1 -(1,2,4-triazol- 1-yl)- 1-p-methoxyphenylcarbonylmethylthio] -4,6-dimethyl-pyrimidine was also determined. It crystallizes in monoclinic system, space group P21/c, a=0.8016(2) nm, b=1.2462(3) nm, c= 1.7824(4) nm,β=99.89(3)°, Z=4, V=1.7540(7) nm3, Dc=1.346 g/cm3, μ=0.205 mm-1, F(000)=744, final R1=0.0452. There is obviously potentially weak C-H…N intermolecular interaction between the molecules in the crystal lattice, which stabilizes the crystal structure. The result of the biological test showed that the four compounds all have some fungicidal and plant growth regulating activities.
