摘要：

A hexachloro metabolite, dysidamide (2) has been isolated from a Red Sea sponge Dysidea herbacea. The structure of (2) has been established from spectroscopic and chemical evidence, and confirmed by an X-ray crystal structure determination. Crystals of (2) are orthorhombic P212121, a 20·509(13), b 18·411(11), c 11·356(9) Å, Z 8. The structure was refined by least-squares methods to a residual of 0·049 for 2277 ‘observed’ reflections. Two different conformations of the molecule are present in the crystal. © 1990 ASEG.
