The structure described by ScMo3O8 is Hydrophilite-derived structured and crystallizes in the triclinic P-1 space group. Sc(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms 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 47-55°. There are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms 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 47-53°. In the second Mo site, Mo(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms 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 48-55°. In the third Mo site, Mo(3) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms 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 50-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted 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 T-shaped 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 trigonal planar geometry to one Sc(1), one Mo(1), and one Mo(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Sc(1), one Mo(1), and one Mo(3) atom. is represented by the CIF file [CIF]
