Mn Mn Sn Au
Mn2AuSn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mn2AuSn clusters. Mn(1) is bonded in an L-shaped geometry to one Au(1) and one Sn(1) atom. The Mn(1)-Au(1) bond length is 0.13 Å. The Mn(1)-Sn(1) bond length is 0.13 Å. Au(1) is bonded in an L-shaped geometry to two equivalent Mn(1) atoms. Sn(1) is bonded in an L-shaped geometry to two equivalent Mn(1) atoms.
