Following is the molecular structure of Lead-molybdenum chromate (CAS NO.12709-98-7) is:

Lead and its compounds, as well as chromium and its compounds, are on the Community Right-To-Know List.

Questionable carcinogen with experimental neoplastigenic and tumorigenic data. Human mutation data reported. A powerful oxidizer. Probably a severe eye, skin, and mucous membrane irritant. When heated to decomposition it emits toxic fumes of Pb, chromium trioxide, and Mo. See also LEAD COMPOUNDS, MOLYBDENUM COMPOUNDS, and CHROMIUM COMPOUNDS.
