The 1H NMR spectrum of the title compound shows that the two hydrogen atoms at a-C are magnetic nonequivalence. To explain the nonequivalence phenomenon, the crystal and molecular structure of the title compound has been determined by X-ray diffraction methed. The crystal (C27H26NO5PS) is monoclinic withspace group P21/c, a = 11. 310(4), b =20. 692(5), c =11. 826(4) A, β =112. 46(3)°， V = 2256(1) A3, Mr- 507. 55, Z = 4, Dx= 1. 319g/cm3, μ= 2. 179cm-1,F(000) =1064, R = 0. 054 and Rw= 0. 064 for 2405 renections with I≥>3δ(I). TheX-ray diffraction analysis reveals that the two hydrogen atoms at a-C are located at differeat magnetic environments, which can explain the nonequivalence phenomnon in 1HNMR spetrum.
