The material structure described by MgScWS4 is Hausmannite-derived structured and crystallizes in the orthorhombic Imma space group. Mg(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form MgS4 tetrahedra that share corners with six equivalent Sc(1)S6 octahedra and corners with six equivalent W(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 57-61°. Sc(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form ScS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Sc(1)S6 octahedra, and edges with four equivalent W(1)S6 octahedra. W(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form WS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent W(1)S6 octahedra, and edges with four equivalent Sc(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Sc(1), and two equivalent W(1) atoms. In the second S site, S(2) is bonded to one Mg(1), two equivalent Sc(1), and one W(1) atom to form a mixture of distorted edge and corner-sharing SMgSc2W trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
