Sn B W W
W2BSn 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 B(1) and four equivalent Sn(1) atoms. There are a spread of W(1)-B(1) bond distances ranging from 2.27-2.52 Å. There are a spread of W(1)-Sn(1) bond distances ranging from 2.84-3.05 Å. In the second W site, W(2) is bonded in a 8-coordinate geometry to four equivalent B(1) and four equivalent Sn(1) atoms. There are a spread of W(2)-B(1) bond distances ranging from 2.55-2.78 Å. There are a spread of W(2)-Sn(1) bond distances ranging from 2.84-3.05 Å. B(1) is bonded in a distorted body-centered cubic geometry to four equivalent W(1) and four equivalent W(2) atoms. Sn(1) is bonded to four equivalent W(1), four equivalent W(2), and four equivalent Sn(1) atoms to form a mixture of distorted face and corner-sharing SnSn4W8 cuboctahedra. All Sn(1)-Sn(1) bond lengths are 2.93 Å.
