MnAu2Sn is Ammonia-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnAu2Sn clusters. Mn(1) is bonded in a single-bond geometry to one Sn(1) atom. The Mn(1)-Sn(1) bond length is 0.50 Å. Au(1) is bonded in a single-bond geometry to one Sn(1) atom. The Au(1)-Sn(1) bond length is 0.87 Å. Sn(1) is bonded in a trigonal non-coplanar geometry to one Mn(1) and two equivalent Au(1) atoms.
