KCoAu3(CN)6 crystallizes in the trigonal P312 space group. K(1) is bonded to six equivalent C(1) and six equivalent N(1) atoms to form KC6N6 cuboctahedra that share edges with three equivalent Co(1)N6 octahedra. Co(1) is bonded to six equivalent N(1) atoms to form CoN6 octahedra that share edges with three equivalent K(1)C6N6 cuboctahedra. Au(1) is bonded in a linear geometry to two equivalent C(1) atoms. C(1) is bonded in a distorted single-bond geometry to one K(1), one Au(1), and one N(1) atom. N(1) is bonded in a distorted linear geometry to one K(1), one Co(1), and one C(1) atom.
