| Abstract: | The crystal structure of the title compound (C17H23O3P, Mr= 306.32) has been preparedand determined by single-crystal X-ray diffraction. The crystal is triclinic, space group P-1 with param-eters:a=9. 852(1), b=9. 887(1), c=19. 949(3) A, α=83. 161(4), β=87. 012(3), γ=66.085(3)°V=1763.7(4) A3, Z=4, Dc=1.154 g/cm3, μ(MoKa)=0.163 mm-1, F(000)=656, the final R=0. 078 5 and wR=0. 185 4 for 2 094 observed reflections with I＞2σ(Ⅰ). The X-ray analysis result con-firms the E configuration of the title compound. |
