Redermination of 9,9'-bianthracene-10,10'(9H,9'H)-dione.

ABSTRACT: The crystal structure of the title compound, C(28)H(18)O(2), was originally determined by Ehrenberg [(1967 ▶). Acta Cryst. 22, 482-487] using intensity data obtained from Weissenberg photographs. The current determination provides a crystal and mol-ecular structure with a significantly higher precision and presents standard uncertainties on geometric parameters which are not available from the original work. The mol-ecule lies on a crystallographic twofold rotation axis which bis-ects the C-C bond [1.603 (3) Å] which joins the two anthracen-9(10H)-one units.
