Two of N′-N′-(4,6-disubstituted-pyrimidin-2-yl)-N-[2-(2,4-dichlorophenoxypropionyl)]thiourea (4a-4b) had been synthesized and their crystal structures had been determined by X-ray diffraction method. 4a crystallizes in the triclinic space group P-1, with a = 8.053(12) Å, α = 102.84(2)°, b = 10.541(16) Å, β = 106.99(2)°, c = 12.461(19) Å, γ = 94.615(19)°, and D c = 1.470 mg/m3 for Z = 2. 4b crystallizes in the triclinic space group P-1, with a = 7.939(5) Å, α = 105.302(10)°, b = 10.183(7) Å, β = 105.729(9)°, c = 12.764(9) Å, γ = 90.698(11)°, and D c = 1.517 mg/m3 for Z = 2. Two pyrimidine derivatives were synthesized and the crystal structures were determined by X-ray diffraction.
