Sr2Sn 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 Sn(1) atoms. In the second Sr site, Sr(2) is bonded to four equivalent Sn(1) atoms to form a mixture of corner and edge-sharing SrSn4 tetrahedra. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Sr(2) and five equivalent Sr(1) atoms.
Sr2Sn 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 Sn(1) atoms. There are a spread of Sr(1)-Sn(1) bond distances ranging from 3.49-3.95 Å. In the second Sr site, Sr(2) is bonded to four equivalent Sn(1) atoms to form a mixture of corner and edge-sharing SrSn4 tetrahedra. There are a spread of Sr(2)-Sn(1) bond distances ranging from 3.33-3.43 Å. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Sr(2) and five equivalent Sr(1) atoms.
