Sn Sn Ru W
WRuSn2 crystallizes in the triclinic P1 space group. W(1) is bonded in a 1-coordinate geometry to five equivalent Ru(1) and one Sn(1) atom. There are a spread of W(1)-Ru(1) bond distances ranging from 2.84-3.69 Å. The W(1)-Sn(1) bond length is 2.46 Å. Ru(1) is bonded in a 11-coordinate geometry to five equivalent W(1), two equivalent Ru(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. Both Ru(1)-Ru(1) bond lengths are 3.07 Å. There is one shorter (2.82 Å) and one longer (3.52 Å) Ru(1)-Sn(1) bond length. There is one shorter (2.80 Å) and one longer (2.92 Å) Ru(1)-Sn(2) bond length. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one W(1), two equivalent Ru(1), and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 0.31 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to two equivalent Ru(1) and one Sn(1) atom.
