Sr2Pb is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. In the second Sr site, Sr(2) is bonded to four equivalent Pb(1) atoms to form a mixture of corner and edge-sharing SrPb4 tetrahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Sr(2) and five equivalent Sr(1) atoms.
Sr2Pb is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. There are a spread of Sr(1)-Pb(1) bond distances ranging from 3.50-4.00 Å. In the second Sr site, Sr(2) is bonded to four equivalent Pb(1) atoms to form a mixture of corner and edge-sharing SrPb4 tetrahedra. There are a spread of Sr(2)-Pb(1) bond distances ranging from 3.36-3.45 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Sr(2) and five equivalent Sr(1) atoms.
