MnRhMnAu crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two gold--manganese (1/1) molecules and two MnRh clusters. In each MnRh cluster, Mn(1) is bonded in a single-bond geometry to one Rh(1) atom. The Mn(1)-Rh(1) bond length is 0.90 Å. Rh(1) is bonded in a distorted single-bond geometry to one Mn(1) atom.
