Dilead(II) trimercury(II) tetraoxide chromate(VI), Pb2(Hg3O4)(CrO4).
Pb2(Hg3O4)(CrO4) consists of [CrO4]2- tetrahedra, linear O-Hg-O dumbbells and divalent Pb atoms in [3+5]-coordination. The HgO2 dumbbells are condensed into [Hg3O4]2- units and can be regarded as a section of the HgO structure. The [Hg3O4]2- complex anions are connected by interstitial Pb2+ ions, while the [CrO4]2- tetrahedra are isolated.
