ReCo2Ge is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ReCo2Ge cluster. Re(1) is bonded in a distorted single-bond geometry to one Co(1), one Co(2), and one Ge(1) atom. The Re(1)-Co(1) bond length is 0.60 Å. The Re(1)-Co(2) bond length is 0.83 Å. The Re(1)-Ge(1) bond length is 1.33 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in an L-shaped geometry to one Re(1) and one Co(2) atom. The Co(1)-Co(2) bond length is 0.60 Å. In the second Co site, Co(2) is bonded in a 3-coordinate geometry to one Re(1), one Co(1), and one Ge(1) atom. The Co(2)-Ge(1) bond length is 1.33 Å. Ge(1) is bonded in a 2-coordinate geometry to one Re(1) and one Co(2) atom.
