Abstract
THE nature of the molecular interaction in the formation of crystalline quinhydrones has been discussed previously by Anderson1. By comparison of preliminary crystallographic data for a number of quinhydrones, he came to the conclusion that the molecules are held together by the interaction of polar groups and polarizable aromatic substances, and that hydrogen-bond formation is not an essential structural feature, though it is not necessarily excluded. We have now been able to confirm these conclusions by a detailed structure determination of phenoquinone (which will be reported in full elsewhere), and by comparison with further preliminary data for quinhydrone and other molecular compounds of this type.
