Lead polonide is the polonide of lead, with the chemical formula of PbPo. It occurs naturally, as lead is produced in the alpha decay of polonium.[3]
Preparation
Lead polonide can be formed by reacting polonium vapour and lead under a vacuum.[4]
Properties
Lead polonide has a sodium chloride structure, which is the same as lead telluride. It has a cubic crystal structure, with the space group Fm3m (No. 225), with lattice constant a = 6.59 Å.[5]
