The crystal structure described by KMgSc(MoO4)2 crystallizes in the trigonal P3m1 space group. K(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Mg(1) is bonded in a single-bond geometry to one O(4) atom. Sc(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form ScO6 octahedra that share corners with three equivalent Mo(1)O4 tetrahedra and corners with three equivalent Mo(2)O4 tetrahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(3) and three equivalent O(2) atoms to form distorted MoO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles are 6°. In the second Mo site, Mo(2) is bonded to one O(4) and three equivalent O(1) atoms to form MoO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one K(1), one Sc(1), and one Mo(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Sc(1), and one Mo(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Mo(1) atom. In the fourth O site, O(4) is bonded in a linear geometry to one Mg(1) and one Mo(2) atom. is represented by the CIF file [CIF]
