Abstract An x-ray structural investigation of crystals of the black modification of 2-(para-dimethylaminophenyl)indan-1,3-dione was carried out. It was found that the molecules in the crystal, which was shown to be the hemihydrate, coexist in the enolic and zwitterion forms. The absence of strong delocalization of the negative charge was shown for the bipolar form. In the crystal, the molecules are bound mutually and with the solvate molecular of water with a system of hydrogen bonds allowing the possible “cooperative” transfer of protons.
