Co Cu Cu Ge
CoCu2Ge is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CoCu2Ge cluster. Co(1) is bonded in a distorted L-shaped geometry to one Cu(1) and one Cu(2) atom. The Co(1)-Cu(1) bond length is 0.79 Å. The Co(1)-Cu(2) bond length is 0.97 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted L-shaped geometry to one Co(1) and one Ge(1) atom. The Cu(1)-Ge(1) bond length is 0.97 Å. In the second Cu site, Cu(2) is bonded in a distorted L-shaped geometry to one Co(1) and one Ge(1) atom. The Cu(2)-Ge(1) bond length is 0.79 Å. Ge(1) is bonded in a distorted L-shaped geometry to one Cu(1) and one Cu(2) atom.
