Preparation
editLead polonide can be formed by reacting polonium vapour and lead under a vacuum.[4]
Properties
editLead 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]
