Article abstract of DOI:10.1107/S0108270195013096

In the title compound, C₇₅H₁₄O₂, a bis(4-methoxyphenyl)methylene group bridges a 6-6-ring junction of the C₆₀ sphere, forming a slightly deformed cyclopropane ring. The C-C bond length involved in the cyclopropane ring fusion is 1.635 (4) A, more than 0.2 A longer than that at the 6-6-ring junction of C₆₀. The elongation of this C-C bond leads to a slight deformation of the C₆₀ framework, especially a shortening of two C-C bonds in equatorial positions.
