Sn Sn Ge Ru
RuSn2Ge crystallizes in the triclinic P1 space group. Ru(1) is bonded in a single-bond geometry to three equivalent Sn(1) and one Ge(1) atom. There are a spread of Ru(1)-Sn(1) bond distances ranging from 3.07-3.51 Å. The Ru(1)-Ge(1) bond length is 1.06 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to three equivalent Ru(1), one Sn(2), and four equivalent Sn(1) atoms. The Sn(1)-Sn(2) bond length is 2.61 Å. There are two shorter (3.21 Å) and two longer (3.26 Å) Sn(1)-Sn(1) bond lengths. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to one Sn(1) and three equivalent Ge(1) atoms. There are a spread of Sn(2)-Ge(1) bond distances ranging from 2.42-2.94 Å. Ge(1) is bonded in a single-bond geometry to one Ru(1) and three equivalent Sn(2) atoms.
