Abstract: The crystal and molecular structures of 2-diethylamino-3-(4'-methylbenzoyl)-2-thione-l, 3, 2-oxazaphospholidine (1) and 2-diethylamino-3-(2', 4'-dichlorobenzoyl)-2-thione-1,3, 2-oxaza-phospholidine(2) were determined by X-ray diffraction method.The diffraction data were collected on a CAD4 single crystal diffractometer.The crystallographic data are as follows; (1) C14H21N2O2PS, orthorhombic, space group Pbca α=0.9057(5) nm, 6=1.3974(6) nm, c=2.5130(7) nm, Z=8, V=3.1806 nm3, R=0.051.(2) C13H17N2O2PSCl2, monoclinic, space group P21/c, α=0.7375(1) nm, 6=1.4370(3) nm, c=l.6015(7) nm, β=93.70(2)°/, Z=4, V=1.6895 nm3, R=0.054.The structures of the two compounds were solved by the direct method.The five-membered oxaza-phospholidine ring has a half chair conformation in both of the molecules.
