Zr Cu Se
CuZrSe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CuZrSe cluster. Zr(1) is bonded in a single-bond geometry to one Se(1) atom. The Zr(1)-Se(1) bond length is 1.44 Å. Cu(1) is bonded in a single-bond geometry to one Se(1) atom. The Cu(1)-Se(1) bond length is 0.56 Å. Se(1) is bonded in a bent 150 degrees geometry to one Zr(1) and one Cu(1) atom.
