摘要：

The crystal structures of 9,10-dihydro-9,10-[o]benzenoanthracene-1,4-dione (TPQ) and its 6,7-dimethyl derivative (6,7-dimethyl-TPQ) were studied. In the latter crystal ribbon-like supramolecules were found to be formed by weak intermolecular pi-pi interactions between quinone and benzene moieties of the molecules. Similar pi-pi interaction seems to be present in TPQ. Moreover, the supramolecules were found to be associated each other by C-H ... O hydrogen bonds to result in three dimensional supramolecules.
