Materials Data on Tb2GdGa5O12 by Materials Project

Abstract

Tb2GdGa5O12 crystallizes in the tetragonal I4_122 space group. The structure is three-dimensional. there are three inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.37 Å) and four longer (2.47 Å) Tb–O bond lengths. In the second Tb3+ site, Tb3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.37 Å) and four longer (2.47 Å) Tb–O bond lengths. In the third Tb3+ site, Tb3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.37 Å) and four longer (2.47 Å) Tb–O bond lengths. Gd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.39 Å) and four longer (2.48 Å) Gd–O bond lengths. There are four inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to six O2- atoms to form corner-sharing GaO6 octahedra. There are five shorter (2.02 Å) and one longer (2.03 Å) Ga–O bond lengths. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. All Ga–O bond lengths are 1.87 Å. In the third Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. All Ga–O bond lengths are 1.87 Å. In the fourth Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. All Ga–O bond lengths are 1.87 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Tb3+, one Gd3+, and two Ga3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Gd3+ and two Ga3+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Tb3+, one Gd3+, and two Ga3+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Tb3+ and two Ga3+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Tb3+ and two Ga3+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two Tb3+ and two Ga3+ atoms.
