Materials Data on Gd2Mo5O18 by Materials Project
Gd2Mo5O18 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.36–2.54 Å. There are three inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form corner-sharing MoO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 1.75–1.91 Å. In the second Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.78 Å) and two longer (1.81 Å) Mo–O bond length. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form corner-sharing MoO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 1.76–1.89 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a linear geometry to one Gd3+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Gd3+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a linear geometry to two Mo6+ atoms. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one Mo6+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Mo6+ atom.
