Rb2LiFe(MoO4)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.90–3.48 Å. In the second Rb1+ site, Rb1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Rb–O bond distances ranging from 3.06–3.46 Å. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four MoO4 tetrahedra. There is two shorter (1.95 Å) and two longer (1.96 Å) Li–O bond length. 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 three equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 41–48°. There are a spread of Mo–O bond distances ranging from 1.75–1.84 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three equivalent LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 38°. There are a spread of Mo–O bond distances ranging from 1.78–1.84 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent FeO6 octahedra and a cornercorner with one LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 14°. There are a spread of Mo–O bond distances ranging from 1.75–1.82 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.99–2.07 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Fe3+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to three Rb1+, one Li1+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Mo6+, and one Fe3+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one Mo6+ and one Fe3+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Rb1+, one Li1+, and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a distorted linear geometry to one Rb1+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a linear geometry to three Rb1+, one Li1+, and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Rb1+, one Mo6+, and one Fe3+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to three Rb1+ and one Mo6+ atom.
