Materials Data on Ho2Ge2O7 by Materials Project
Abstract
Ho2Ge2O7 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ho3+ is bonded to six O2- atoms to form distorted HoO6 pentagonal pyramids that share corners with six equivalent GeO4 tetrahedra and edges with three equivalent HoO6 pentagonal pyramids. There are a spread of Ho–O bond distances ranging from 2.24–2.32 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with six equivalent HoO6 pentagonal pyramids and a cornercorner with one GeO4 tetrahedra. All Ge–O bond lengths are 1.77 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ho3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ho3+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a linear geometry to two equivalent Ge4+ atoms.
