Sn W W Au
W2AuSn crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 8-coordinate geometry to four equivalent Au(1) and four equivalent Sn(1) atoms. There are a spread of W(1)-Au(1) bond distances ranging from 2.41-3.02 Å. There are a spread of W(1)-Sn(1) bond distances ranging from 2.76-3.31 Å. In the second W site, W(2) is bonded in a 8-coordinate geometry to four equivalent Au(1) and four equivalent Sn(1) atoms. There are a spread of W(2)-Au(1) bond distances ranging from 2.41-3.02 Å. There are a spread of W(2)-Sn(1) bond distances ranging from 2.68-3.24 Å. Au(1) is bonded in a 8-coordinate geometry to four equivalent W(1) and four equivalent W(2) atoms. Sn(1) is bonded in a 8-coordinate geometry to four equivalent W(1) and four equivalent W(2) atoms.
