The crystal structure described by ScMo3O8 is Hydrophilite-derived structured and crystallizes in the triclinic P1 space group. Sc(1) is bonded to one O(1), one O(3), one O(4), one O(5), one O(7), and one O(8) atom to form ScO6 octahedra that share corners with four equivalent Mo(1)O6 octahedra, corners with four equivalent Mo(2)O6 octahedra, and corners with four equivalent Mo(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. There are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(8) atom to form MoO6 octahedra that share corners with four equivalent Sc(1)O6 octahedra, edges with two equivalent Mo(2)O6 octahedra, and edges with two equivalent Mo(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. In the second Mo site, Mo(2) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form MoO6 octahedra that share corners with four equivalent Sc(1)O6 octahedra, edges with two equivalent Mo(1)O6 octahedra, and edges with two equivalent Mo(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. In the third Mo site, Mo(3) is bonded to one O(1), one O(2), one O(4), one O(6), one O(7), and one O(8) atom to form MoO6 octahedra that share corners with four equivalent Sc(1)O6 octahedra, edges with two equivalent Mo(1)O6 octahedra, and edges with two equivalent Mo(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-51°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Sc(1), one Mo(2), and one Mo(3) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Mo(1), one Mo(2), and one Mo(3) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Sc(1), one Mo(1), and one Mo(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Sc(1), one Mo(1), and one Mo(3) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Sc(1), one Mo(1), and one Mo(2) atom. In the sixth O site, O(6) is bonded in a distorted T-shaped geometry to one Mo(1), one Mo(2), and one Mo(3) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one Sc(1), one Mo(2), and one Mo(3) atom. In the eighth O site, O(8) is bonded in a trigonal planar geometry to one Sc(1), one Mo(1), and one Mo(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
