The structure of the π-molecular complex (10) was assigned on the basis of the solid state ¹³C-nmr spectrum. The solid state ¹³C-nmr spectrum of quinhydrone (12) has also been determined. Accurate ¹H and ¹³C chemical shift assignments have been made for the compounds 3, 5, 6, 7, 8, and 10 on the basis of HMQC and HMBC spectral data. The π-molecular complex 10 crystallizes in the space group P2₁/n with cell parameters: a = 4.052 (1) A?, b = 6.477 (1) A?, c = 19.093 (2) A?, β = 90.17 (1)°, z = 1, D_c = 1.400 g cm^-3. Crystal and molecular structure of the title compound, C₂₈H₂₂O₄, has been determined by an X-ray analysis of 10 by direct methods from diffractometer data and refined by full-matrix least-squares.
