Materials Data on Er2Mo4O15 by Materials Project
Er2.0Mo4O15 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Er3+ is bonded to seven O2- atoms to form ErO7 pentagonal bipyramids that share corners with seven MoO4 tetrahedra. There are a spread of Er–O bond distances ranging from 2.25–2.36 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with four equivalent ErO7 pentagonal bipyramids. There are a spread of Mo–O bond distances ranging from 1.78–1.82 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form distorted MoO4 tetrahedra that share corners with three equivalent ErO7 pentagonal bipyramids and a cornercorner with one MoO4 tetrahedra. There are a spread of Mo–O bond distances ranging from 1.77–1.90 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Er3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Er3+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to one Er3+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Er3+ and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a linear geometry to two equivalent Mo6+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Er3+ and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Er3+ and one Mo6+ atom.
