Crystal structure of the title compound C 16 H 25 O 2NS 2 has been determined by X-ray diffraction method. Its crystallographic data were as follows: M r=327.51, triclinic, space group P1, a=8.864(3), b=10.127(4), c=10.390(3) , α=105.94(3), β=103.10(2), γ=90.96(3)°, V=870.3(7) 3, Z=2, D c=1.250g.cm -3 , μ(MoKα)=2.966cm -1 , F(000)=176, a total of 3275 reflections measured (2θ max =50°), 2246[I5σ(I)] used in the refinement, R=0.067, R w=0.082. The result shows that the distances of N(1)-C(2) and N(1)-C(3) are longer than that of N(1)-C(11), which indicates that the interaction of C Ar -N sp 2 is stronger than that of C sp 3 -N sp 2 . Oxygen, nitrogen and sulfur atoms of the ring in the same plane was deduced from the least|squares planes and the dihedral angles.
