Sc Mn Mn Au
ScMn2Au crystallizes in the trigonal R3m space group. Sc(1) is bonded in a 1-coordinate geometry to one Mn(2), three equivalent Mn(1), and one Au(1) atom. The Sc(1)-Mn(2) bond length is 2.30 Å. All Sc(1)-Mn(1) bond lengths are 2.72 Å. The Sc(1)-Au(1) bond length is 2.16 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 7-coordinate geometry to three equivalent Sc(1), one Mn(2), and three equivalent Au(1) atoms. The Mn(1)-Mn(2) bond length is 2.16 Å. All Mn(1)-Au(1) bond lengths are 2.72 Å. In the second Mn site, Mn(2) is bonded in a 5-coordinate geometry to one Sc(1), one Mn(1), and three equivalent Au(1) atoms. All Mn(2)-Au(1) bond lengths are 2.72 Å. Au(1) is bonded in a 1-coordinate geometry to one Sc(1), three equivalent Mn(1), and three equivalent Mn(2) atoms.
