MgLaVS4 is Spinel-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 La(1)S6 octahedra and corners with six equivalent V(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 46-67°. La(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form LaS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent La(1)S6 octahedra, and edges with four equivalent V(1)S6 octahedra. V(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form VS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent V(1)S6 octahedra, and edges with four equivalent La(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), one La(1), and two equivalent V(1) atoms. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent La(1), and one V(1) atom.
