Dy Dy Mn Pb
Dy2MnPb crystallizes in the trigonal R3m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a distorted linear geometry to four equivalent Mn(1) and one Pb(1) atom. There is one shorter (2.46 Å) and three longer (3.40 Å) Dy(1)-Mn(1) bond lengths. The Dy(1)-Pb(1) bond length is 2.46 Å. In the second Dy site, Dy(2) is bonded in a distorted single-bond geometry to three equivalent Mn(1) and one Pb(1) atom. All Dy(2)-Mn(1) bond lengths are 3.09 Å. The Dy(2)-Pb(1) bond length is 2.46 Å. Mn(1) is bonded in a 10-coordinate geometry to three equivalent Dy(2), four equivalent Dy(1), and three equivalent Pb(1) atoms. All Mn(1)-Pb(1) bond lengths are 3.04 Å. Pb(1) is bonded in a distorted linear geometry to one Dy(1), one Dy(2), and three equivalent Mn(1) atoms.
