Dy5Pb4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to one Pb(3), two equivalent Pb(2), and three equivalent Pb(1) atoms to form a mixture of distorted face, corner, and edge-sharing DyPb6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 39-41°. In the second Dy site, Dy(2) is bonded in a 7-coordinate geometry to one Pb(2), two equivalent Pb(3), and four equivalent Pb(1) atoms. In the third Dy site, Dy(3) is bonded to two equivalent Pb(1), two equivalent Pb(2), and two equivalent Pb(3) atoms to form a mixture of face and corner-sharing DyPb6 octahedra. The corner-sharing octahedral tilt angles range from 45-51°. There are three inequivalent Pb sites. In the first Pb site, Pb(3) is bonded in a 8-coordinate geometry to two equivalent Dy(1), two equivalent Dy(3), and four equivalent Dy(2) atoms. In the second Pb site, Pb(1) is bonded in a 8-coordinate geometry to one Dy(3), three equivalent Dy(1), and four equivalent Dy(2) atoms. In the third Pb site, Pb(2) is bonded in a 8-coordinate geometry to two equivalent Dy(2), two equivalent Dy(3), and four equivalent Dy(1) atoms.
