Dipotassium rhodizonate, 2K + ·C 6 O 6 2− , crystallizes in space group Fddd . The rhodizonate anions lie in hexagonal layers connected by the potassium ions, which lie between the planes and connect adjacent layers. The conformation of the rhodizonate ion is distinct from previous observations. The site symmetry of the potassium ions is 2 and the site symmetry of the centroid of the rhodizonate ions is 222.
