Y Mn Mn Pb
YMn2Pb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YMn2Pb cluster. Y(1) is bonded in a single-bond geometry to one Mn(2) and one Pb(1) atom. The Y(1)-Mn(2) bond length is 0.51 Å. The Y(1)-Pb(1) bond length is 2.05 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Mn(1)-Pb(1) bond length is 1.98 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Y(1) and one Pb(1) atom. The Mn(2)-Pb(1) bond length is 1.98 Å. Pb(1) is bonded in a 3-coordinate geometry to one Y(1), one Mn(1), and one Mn(2) atom.
