Materials Data on ErGeBiO5 by Materials Project
BiErGeO5 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Er3+ is bonded to seven O2- atoms to form distorted ErO7 pentagonal bipyramids that share corners with five equivalent GeO4 tetrahedra and edges with three equivalent ErO7 pentagonal bipyramids. There are a spread of Er–O bond distances ranging from 2.29–2.40 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with five equivalent ErO7 pentagonal bipyramids. There are a spread of Ge–O bond distances ranging from 1.76–1.80 Å. Bi3+ is bonded in a distorted pentagonal planar geometry to five O2- atoms. There are a spread of Bi–O bond distances ranging from 2.18–2.35 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Er3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Er3+, one Ge4+, and one Bi3+ atom. In the third O2- site, O2- is bonded to two equivalent Er3+ and two equivalent Bi3+ atoms to form edge-sharing OEr2Bi2 tetrahedra. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Er3+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Ge4+ and two equivalent Bi3+ atoms.
