| Abstract: | The crystal structure of the title compound, C32H28N2O4 was determined by X-ray diffraction method. Crystallographic data are as follows: Mr =504. 59, monoclinic, space group P21/c with cell dimensions of a = 11. 778 (3), b=8. 416(3), c=26. 310(6) A, β= 95. 74 (2)°, V= 2594. 72(2) A3, Z=4, Dc=1. 292g. cm-3, μ=0. 80cm-1, F(000) = 1064, R=0. 045, m= 0. 048 for 1124 reflections with I≥3(I). The molecule of the title compound has T style structure. Thelactone-benzene group is nearly perpendicular to the xanthene moiety. The C-O bondin the lactone ring is 1. 516(8) A, which is longer than that in the normal lactonering, and this indicates severe weakness of the bond. |
