Re Ge Ru Ru
ReRu2Ge crystallizes in the triclinic P1 space group. Re(1) is bonded in a distorted single-bond geometry to two equivalent Ru(1), two equivalent Ru(2), and one Ge(1) atom. There is one shorter (2.52 Å) and one longer (2.79 Å) Re(1)-Ru(1) bond length. There is one shorter (2.18 Å) and one longer (2.50 Å) Re(1)-Ru(2) bond length. The Re(1)-Ge(1) bond length is 0.84 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 8-coordinate geometry to two equivalent Re(1), two equivalent Ru(1), two equivalent Ru(2), and two equivalent Ge(1) atoms. Both Ru(1)-Ru(1) bond lengths are 2.82 Å. There is one shorter (1.66 Å) and one longer (2.95 Å) Ru(1)-Ru(2) bond length. There is one shorter (2.18 Å) and one longer (2.50 Å) Ru(1)-Ge(1) bond length. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to two equivalent Re(1), two equivalent Ru(1), two equivalent Ru(2), and two equivalent Ge(1) atoms. Both Ru(2)-Ru(2) bond lengths are 2.82 Å. There is one shorter (2.52 Å) and one longer (2.79 Å) Ru(2)-Ge(1) bond length. Ge(1) is bonded in a distorted single-bond geometry to one Re(1), two equivalent Ru(1), and two equivalent Ru(2) atoms.
