Abstract Crystals of the title compound, C12H18O8, are orthorhombic:P212121,a = 7·260(5),b = 9·483(6),c = 20·199(6) Å,Z = 4. The structure has been solved from the Patterson synthesis, and refined to anR-factor of 8·4% by full-matrix least-squares methods. The 6-membered rings are each in thechair conformation and arecis-fused at the 4a, 8a ring-junction. The structure led to an explanation of an unusually large chemical shift in the nmr signal from one of the methylenic hydrogen atoms on C(7).
