The material described by Ho5Pb4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to one Pb(3), two equivalent Pb(2), and three equivalent Pb(1) atoms to form a mixture of distorted corner, edge, and face-sharing HoPb6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 39-41°. In the second Ho site, Ho(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 Ho site, Ho(3) is bonded to two equivalent Pb(1), two equivalent Pb(2), and two equivalent Pb(3) atoms to form a mixture of corner and face-sharing HoPb6 octahedra. The corner-sharing octahedral tilt angles range from 46-51°. There are three inequivalent Pb sites. In the first Pb site, Pb(3) is bonded in a 8-coordinate geometry to two equivalent Ho(1), two equivalent Ho(3), and four equivalent Ho(2) atoms. In the second Pb site, Pb(1) is bonded in a 8-coordinate geometry to one Ho(3), three equivalent Ho(1), and four equivalent Ho(2) atoms. In the third Pb site, Pb(2) is bonded in a 8-coordinate geometry to two equivalent Ho(2), two equivalent Ho(3), and four equivalent Ho(1) atoms. is represented by the CIF card [CIF]
