Crystals of the title compound are orthorhombic with a - 8,483(4), b -18,249(9), c 15,889(8) A, space group Pbca, Ζ = 8. The quinone ring shows distinct distortions from planarity. The solution n.m.r. spectra of the compound at various temperatures suggest a measure of restricted rotation about the cyclopropyl-quinonoid bonds. This is partially substantiated by a conformational analysis using the method of atom pair potentials.
