Mn Mn B Au
Mn2AuB crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mn2AuB clusters. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Au(1) atom. The Mn(1)-Au(1) bond length is 1.24 Å. In the second Mn site, Mn(2) is bonded in a 2-coordinate geometry to one Au(1) and one B(1) atom. The Mn(2)-Au(1) bond length is 1.37 Å. The Mn(2)-B(1) bond length is 1.39 Å. Au(1) is bonded in a distorted L-shaped geometry to one Mn(1) and one Mn(2) atom. B(1) is bonded in a distorted single-bond geometry to one Mn(2) atom.
