Sn Ge W W
W2SnGe crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Sn(1) and two equivalent Ge(1) atoms. There is one shorter (2.25 Å) and one longer (3.01 Å) W(1)-Sn(1) bond length. There is one shorter (1.41 Å) and one longer (1.95 Å) W(1)-Ge(1) bond length. In the second W site, W(2) is bonded in a 2-coordinate geometry to two equivalent Sn(1) and one Ge(1) atom. There is one shorter (1.82 Å) and one longer (3.09 Å) W(2)-Sn(1) bond length. The W(2)-Ge(1) bond length is 1.82 Å. Sn(1) is bonded in a 5-coordinate geometry to two equivalent W(1), two equivalent W(2), and one Ge(1) atom. The Sn(1)-Ge(1) bond length is 1.85 Å. Ge(1) is bonded in a 4-coordinate geometry to one W(2), two equivalent W(1), and one Sn(1) atom.
