Ge Ge Ru Se
RuGeGeSe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one germanium(ii) selenide molecule and one RuGe cluster. In the RuGe cluster, Ru(1) is bonded in a single-bond geometry to one Ge(2) atom. The Ru(1)-Ge(2) bond length is 1.19 Å. Ge(2) is bonded in a single-bond geometry to one Ru(1) atom.
