Materials Data on Ho2Pb2O7 by Materials Project

Ho2Pb2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Ho3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.33 Å) and six longer (2.49 Å) Ho–O bond lengths. Pb4+ is bonded to six equivalent O2- atoms to form distorted corner-sharing PbO6 octahedra. The corner-sharing octahedral tilt angles are 59°. All Pb–O bond lengths are 2.19 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Ho3+ and two equivalent Pb4+ atoms to form a mixture of edge and corner-sharing OHo2Pb2 tetrahedra. In the second O2- site, O2- is bonded to four equivalent Ho3+ atoms to form a mixture of edge and corner-sharing OHo4 tetrahedra.
