| Abstract: | The crystal structure of the title compound(C20 H20O4,Mr.=324.36)has been determined by single crystal X-ray diffraction.The crystal is monoclinic with space group P21/c,a=9.506(1),b=14.499(9),c=12.077(1)A,β=93.55(3)°,V=1661.3(3)A3,Z=4,Dc=1.297g/cm3,λ=0.71073 A,μ(MoKα)=0.090mm-1,F(000)=688.The structrue was refined to R=0.0516,wR(F2)=0.1266 for 2947 reflections with I ＞ 2σ(Ⅰ).X-ray diffraction analysis reveals that the title compound is a pseudo-dimer of benzofuran and there is a chiral carbon atom which causes the two neighbor hydrogen atoms magnetically nonequivalent. |
