Eu2(MoO4)3 crystallizes in the orthorhombic Pba2 space group. The structure is three-dimensional. there are two inequivalent Eu3+ sites. In the first Eu3+ site, Eu3+ is bonded to seven O2- atoms to form distorted EuO7 pentagonal bipyramids that share corners with seven MoO4 tetrahedra and an edgeedge with one EuO7 pentagonal bipyramid. There are a spread of Eu–O bond distances ranging from 2.31–2.51 Å. In the second Eu3+ site, Eu3+ is bonded to seven O2- atoms to form distorted EuO7 pentagonal bipyramids that share corners with seven MoO4 tetrahedra and an edgeedge with one EuO7 pentagonal bipyramid. There are a spread of Eu–O bond distances ranging from 2.29–2.50 Å. There are three inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with five EuO7 pentagonal bipyramids. There are a spread of Mo–O bond distances ranging from 1.78–1.83 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with five EuO7 pentagonal bipyramids. There are a spread of Mo–O bond distances ranging from 1.78–1.83 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with four EuO7 pentagonal bipyramids. All Mo–O bond lengths are 1.79 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Eu3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one Eu3+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Eu3+ and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a linear geometry to one Eu3+ and one Mo6+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Eu3+ and one Mo6+ atom. In the twelfth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Eu3+ and one Mo6+ atom.
