Redermination of 9,9′-bianthracene-10,10′(9H,9′H)-dione
The crystal structure of the title compound, C28H18O2, 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 molecular structure with a significantly higher preci...

Summary: | The crystal structure of the title compound, C28H18O2, 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 molecular structure with a significantly higher precision and presents standard uncertainties on geometric parameters which are not available from the original work. The molecule lies on a crystallographic twofold rotation axis which bisects the C—C bond [1.603 (3) Å] which joins the two anthracen-9(10H)-one units. |
