Crystals of the title compound with formula C(17)H(19)N2OPS(Mr=330. 4) are monoclinic system space group P21/n,with cell parameters a = 9. 641 (2), b=12. 425(3) ,c=14. 412(5) A , β= 95. 11(2)°,V= 1719(1) A￣3, Z=4,Dx= 1. 276 g/cm￣3, P= 2. 74cm-1, F(000) =696. The final refinement with 1714 observed reflections is converged with R= 0. 049 and Rw= 0. 054. The five-mem-bered heterocycle is in envelope conformation. The P-N bond length (1. 682 A ) indicates a considerable degree of π bonding. In the crystal, there is one intermolecular hydrogen bond O…H(2)-N (2)with O…N (2) distance of 2. 83 A, O…H(2)-N (2) angle of 174. 5°and P-O…H(2) angle of 146. 1°, making molecules to form a chain.
