摘要：

7-Methoxy-2-methyl-4,5-dihydroxy-9,10-anthracenedione, physcion, C16H12O5, M(r) = 284.27, orthorhombic, P2(1)2(1)2(1), a = 3.850 (1), b = 23.73 (3), c = 13.667 (9) angstrom, V = 1249 (2) angstrom 3, Z = 4, D(m) = 1.50 (2), D(x) = 1.51 Mg m-3, lambda(Cu K-alpha) = 1.54178 angstrom, mu = 0.903 mm-1, F(000) = 592, T = 293 K, final R = 0.0594 for 1190 unique reflections with F > 4-sigma(F). The crystal structure consists of planar molecules which are situated in the bc plane and form a densely packed arrangement. The structure of physcion differs from both unsubstituted and 1-acetyl-2,4,5,7-tetrahydroxy-9,10-substituted anthracenedione.
