Zn Sn Sn W
WZnSn2 crystallizes in the monoclinic Cm space group. W(1) is bonded in a 8-coordinate geometry to one Zn(1) and eight equivalent Sn(1) atoms. The W(1)-Zn(1) bond length is 3.24 Å. There are a spread of W(1)-Sn(1) bond distances ranging from 2.73-3.20 Å. Zn(1) is bonded in a 11-coordinate geometry to one W(1), two equivalent Zn(1), and eight equivalent Sn(1) atoms. Both Zn(1)-Zn(1) bond lengths are 3.02 Å. There are a spread of Zn(1)-Sn(1) bond distances ranging from 2.73-3.20 Å. Sn(1) is bonded in a 8-coordinate geometry to four equivalent W(1) and four equivalent Zn(1) atoms.
