Nd2Zn5Pb crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 15-coordinate geometry to one Zn(3), six equivalent Zn(1), six equivalent Zn(2), and two equivalent Pb(1) atoms. In the second Nd site, Nd(2) is bonded in a 14-coordinate geometry to two equivalent Zn(1), four equivalent Zn(2), four equivalent Zn(3), and four equivalent Pb(1) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 10-coordinate geometry to one Nd(2), three equivalent Nd(1), one Zn(1), two equivalent Zn(3), and three equivalent Zn(2) atoms. In the second Zn site, Zn(2) is bonded in a 1-coordinate geometry to two equivalent Nd(2), three equivalent Nd(1), three equivalent Zn(1), and one Pb(1) atom. In the third Zn site, Zn(3) is bonded in a distorted single-bond geometry to one Nd(1), four equivalent Nd(2), four equivalent Zn(1), and one Pb(1) atom. Pb(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Zn(3), and two equivalent Zn(2) atoms.
