Lead carbonate

Structure

Like all metal carbonates, lead(II) carbonate adopts a dense, highly crosslinked structure consisting of intact and metal cation sites. As verified by X-ray crystallography, the Pb(II) centers are seven-coordinate, being surrounded by multiple carbonate ligands. The carbonate centers are bonded bidentate to a single Pb and bridge to five other Pb sites.

Production and use

Lead carbonate is manufactured by passing carbon dioxide into a cold dilute solution of lead(II) acetate, or by shaking a suspension of a lead salt more soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate.

:

Lead carbonate is used as a catalyst to polymerize formaldehyde to poly(oxymethylene). It improves the bonding of chloroprene to wire.

Regulations

The supply and use of this compound is restricted in Europe.

Other lead carbonates

A number of lead carbonates are known:

• White lead, a basic lead carbonate,
• Shannonite,
• Plumbonacrite,
• Abellaite,
• Leadhillite,
