Mn Au Au
Au2Mn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Au2Mn clusters. Mn(1) is bonded in a single-bond geometry to one Au(1) atom. The Mn(1)-Au(1) bond length is 0.09 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Mn(1) and one Au(2) atom. The Au(1)-Au(2) bond length is 0.92 Å. In the second Au site, Au(2) is bonded in a single-bond geometry to one Au(1) atom.
