The crystal structure described by MgV2(SbO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(2), one O(3), one O(4), and one O(8) atom to form distorted MgO4 tetrahedra that share corners with four equivalent Sb(2)O6 octahedra,  an edgeedge with one V(2)O6 octahedra, and  an edgeedge with one V(1)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 2-47°. There are two inequivalent V sites.
