Mn Ge Ru Ru
Ru2MnGe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ru2MnGe cluster. Mn(1) is bonded in a single-bond geometry to one Ru(1) atom. The Mn(1)-Ru(1) bond length is 0.51 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Ge(1) atom. The Ru(1)-Ge(1) bond length is 1.58 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Ge(1) atom. The Ru(2)-Ge(1) bond length is 0.49 Å. Ge(1) is bonded in a distorted single-bond geometry to one Ru(1) and one Ru(2) atom.
