The crystal structure of the title compound C 16H 17N 2OPS 2, has been determined by single-crystal X-ray diffraction at 299K. The crystal is monoclinic with space group P2 1/n, a=9.549(2), b=7.954(5), c=23.039(8) Å, β=96.30(2)°, V=1739(2) A° 3, Z=4, M,=348.3, F(000)=728, μ(MoKα)=0.386 mm -1, D c= 1.331 g/cm 3. The final R factor is 0.044 and R w is 0.047 for 1002 observed reflections [I≥3σ(I)]. The five-membered heterocycle has a coplanar structure. The P-N(1) bond length (1.636 Å) indicates the existence of the d-p π bond between P and N(1) atoms of the title compound.
