Ge Sb Ru Ru
Ru2GeSb crystallizes in the triclinic P1 space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Ge(1) and two equivalent Sb(1) atoms. The Ru(1)-Ge(1) bond length is 0.60 Å. There is one shorter (2.74 Å) and one longer (3.25 Å) Ru(1)-Sb(1) bond length. In the second Ru site, Ru(2) is bonded in a distorted single-bond geometry to one Ge(1) and two equivalent Sb(1) atoms. The Ru(2)-Ge(1) bond length is 1.67 Å. There is one shorter (2.74 Å) and one longer (3.26 Å) Ru(2)-Sb(1) bond length. Ge(1) is bonded in a 2-coordinate geometry to one Ru(1), one Ru(2), and one Sb(1) atom. The Ge(1)-Sb(1) bond length is 2.82 Å. Sb(1) is bonded in a 7-coordinate geometry to two equivalent Ru(1), two equivalent Ru(2), one Ge(1), and two equivalent Sb(1) atoms. Both Sb(1)-Sb(1) bond lengths are 3.09 Å.
