Mn Pb Au Au
MnAu2Pb is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnAu2Pb clusters. Mn(1) is bonded in a 3-coordinate geometry to two equivalent Au(1) and one Pb(1) atom. Both Mn(1)-Au(1) bond lengths are 0.91 Å. The Mn(1)-Pb(1) bond length is 1.03 Å. Au(1) is bonded in a 2-coordinate geometry to one Mn(1) and one Pb(1) atom. The Au(1)-Pb(1) bond length is 0.91 Å. Pb(1) is bonded in a 3-coordinate geometry to one Mn(1) and two equivalent Au(1) atoms.
