The material described by RbMgFe(MoO4)2 crystallizes in the trigonal P3 space group. Rb(1) is bonded in a 7-coordinate geometry to one Mg(1), three equivalent O(2), and three equivalent O(4) atoms. Mg(1) is bonded in a 3-coordinate geometry to one Rb(1) and three equivalent O(1) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(4) and three equivalent O(2) atoms to form MoO4 tetrahedra that share corners with three equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 22°. In the second Mo site, Mo(2) is bonded to one O(3) and three equivalent O(1) atoms to form MoO4 tetrahedra that share corners with three equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 29°. Fe(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form FeO6 octahedra that share corners with three equivalent Mo(1)O4 tetrahedra and corners with three equivalent Mo(2)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one Mo(2), and one Fe(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Mo(1), and one Fe(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Mo(2) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to three equivalent Rb(1) and one Mo(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
