Re Ge Ru Ru
ReRu2Ge crystallizes in the monoclinic Cm space group. Re(1) is bonded in a single-bond geometry to one Ru(2) and four equivalent Ge(1) atoms. The Re(1)-Ru(2) bond length is 0.87 Å. There are a spread of Re(1)-Ge(1) bond distances ranging from 2.73-2.88 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 9-coordinate geometry to four equivalent Ru(1), four equivalent Ru(2), and one Ge(1) atom. All Ru(1)-Ru(1) bond lengths are 2.95 Å. There are a spread of Ru(1)-Ru(2) bond distances ranging from 2.40-2.57 Å. The Ru(1)-Ge(1) bond length is 2.64 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Re(1) and four equivalent Ru(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Re(1), one Ru(1), and four equivalent Ge(1) atoms. All Ge(1)-Ge(1) bond lengths are 2.95 Å.
