Dilead mercury chromate(VI), Pb2HgCrO6.
The structure of Pb(2)HgCrO(6) (space group P-1) can be described as consisting of isolated [CrO(4)](2-) tetrahedra and nearly linear [HgO(2)](2-) dumb-bells, which form layers of composition [HgCrO(6)](4-). These are intercalated with corrugated pseudo-hexagonal Pb(2+) layers. The Pb(2+) cation is stereochemically active and has coordination 3+5.
