The crystal structure of 9,9,10,10-tetrachloroanthracene has been determined by x-ray analysis. The structure is characterized by dovetailed packing of crystallographically independent molecules. The anthracene skeletons are planar, and the molecules have approximately D2h symmetry. Bond distances and angles are summarized and the stereochemical implications of the results are discussed.
