<正> Compound C9H19N2OPS (1) , Mr = 234. 3, monoclinic, space group P21, a = 7. 5637(2), b = 7. 704(2), c=10. 258(1) (?) ,β = 98. 66(2)°, V = 590. 9(?)3, Z =2, Dc=1. 317g/cm3, F(000) = 252. The final R = 0. 063 and Rw = 0. 080 with unit weight for 870 observed reflections (I≥3σ(I)).

Both skeletons of (1) and (2) have similar geometry, which is composed of three rings : a seven-membered ring in a boat form, a six-membered ring in a chair conformation, and a five-membered ring in envelope form. The configura-tions of the chiral phosphorus atoms are assigned as 3R for (1) and as 3S for (2).
