CoAuTe2 crystallizes in the monoclinic Cm space group. Co(1) is bonded in a 4-coordinate geometry to two equivalent Au(1) and two equivalent Te(1) atoms. There is one shorter (2.35 Å) and one longer (2.55 Å) Co(1)-Au(1) bond length. Both Co(1)-Te(1) bond lengths are 2.52 Å. Au(1) is bonded in a distorted see-saw-like geometry to two equivalent Co(1) and two equivalent Te(1) atoms. Both Au(1)-Te(1) bond lengths are 1.70 Å. Te(1) is bonded in a distorted single-bond geometry to one Co(1) and one Au(1) atom.
