K Rh Rh Au
KRh2Au crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KRh2Au clusters. K(1) is bonded in a 2-coordinate geometry to two equivalent Rh(1) atoms. Both K(1)-Rh(1) bond lengths are 0.44 Å. Rh(1) is bonded in a single-bond geometry to one K(1) and one Au(1) atom. The Rh(1)-Au(1) bond length is 0.97 Å. Au(1) is bonded in a 2-coordinate geometry to two equivalent Rh(1) atoms.
