摘要：The racemic title compound, C(54)H(38)O(2), consists of two C-linked penta-leno[1,2,3-ij]naphthalenone moieties, the crowded aryl ring substitution on the cyclo-pentane rings forcing the two segments to assume a conformation which has pseudo-twofold rotational symmetry, with a dihedral angle between the naphthalene substituent groups of 55.30 (8)°. In each segment, the two phenyl rings have different conformational orientations, with inter-ring dihedral angles of 34.7 (2) and 49.63 (16)°. Each cyclo-pentane ring has the same relative configuration in its four chiral centres and together with the fused naphthalene ring assumes an overall chair-like conformation.
