Abstract:The title compound, C_(38)H_(34)N)2O_3,was synthesized and its crystal structure was determined by X-ray diffraction method. The crystal belongs to monoclinic,space group Cc,with a=16.826(4),b=10.648(4),c=17. 618(7),β=92. 25(2)°,V=3154(2),Z=4,M_r=566. 7,D_x= 1.19 g/cm ̄3 , F(000) =1200.The structure was solved by direct methods.The final R= 0.080.The molecule has a Y style structure which is composed of two parts of butterfly-like xanthene and almost planar isobenzofuran. Two benzene rings of the dibenzylamino stand on two sites of the xanthene respectively.
Keywords:crystal structure  isobenzofuran  xanthene
