Supramolecular architectures of simple aminoanthraquinones: Revised structure of 1-aminoanthraquinone

The solid-state supramolecular architectures of 1-aminoanthraquinone and 1, 5-diaminoanthraquinone were determined by single-crystal X-ray structural analysis. In this paper, revised model − in space group P21/c − is given for the crystal structure of 1-aminanthraquinone. 1-Aminoantaquinone molecules are joined together in infinite chains by N− H· · · O hydrogen bonds which are stacked by face-to-face and edge-to-face π − π interactions thus creating layers and the characteristic herring-bone motif. In the structure of 1, 5-diaminoanthraquinone, the molecules are connected via N− H· · · O hydrogen bonds in the 2D networks of (4, 4) topology. These molecular networks are further stacked by face-to-face π − π and carbonyl− π interactions. The supramolecular organizations of these two compounds are compared with other simple aminoanthraquinones (with at least one non-substituted amino group) thus providing more insights into the basic principles of the solid-state assembling for this class of molecules.
