Synthesis and single crystal structure analysis of three novel benzoylthiourea derivatives

摘要

N, N-dimethyl-N'-(2-methylbenzoyl)thiourea, C_(11)H_(14) N2SO (HL~1), N, N-dibutyl-N'-(2-methylben-zoyl)thiourea, C_(17)H_(26) N2 SO (HL~2), and N, N-dihexyl-N'-(2-methylbenzoyl) thiourea, C_(21)H_(34)N2 SO (HL~3) were synthesized and characterized by elemental analysis, spectroscopic methods (FT-IR, NMR), and single crystal X-ray diffraction. Compound HL~1 crystallizes in the monoclinic system, space group P2_1/c, Z = 4. Compound HL3 also crystallizes in the monoclinic system, space group P2_1, Z = 8 with 2 independent molecules in the asymmetric unit. Compound HL crystallizes in the orthorhombic system, space group Pcnn, Z= 8. In all compounds, molecules form dimers through the strong intermolecular N-H... S hydrogen bonds. Moreover, there are different types of intra- and inter-molecular interactions in the crystal structures, and so the molecules of the 3 compounds also pack differently.
