Ba2Pb is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 3-coordinate geometry to five equivalent Pb(1) atoms. In the second Ba site, Ba(2) is bonded to four equivalent Pb(1) atoms to form a mixture of corner and edge-sharing BaPb4 tetrahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ba(2) and five equivalent Ba(1) atoms.
