摘要
The asymmetric unit of the title compound, C42H24, contains two almost identical mol-ecules. The mol-ecules have approximate D2 symmetry. They show a largely twisted double bond, the mol-ecular halves enclosing dihedral angles of 62.86 (4) and 61.22 (3)°. The crystal studied was twinned by non-merohedry.
