AgMgVO4 crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra, corners with six equivalent Ag(1)O4 trigonal pyramids, and edges with two equivalent Mg(1)O6 octahedra. V(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form VO4 tetrahedra that share corners with six equivalent Mg(1)O6 octahedra and corners with four equivalent Ag(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 42-55°. Ag(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form distorted AgO4 trigonal pyramids that share corners with six equivalent Mg(1)O6 octahedra and corners with four equivalent V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 73-79°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1), one V(1), and one Ag(1) atom to form distorted corner-sharing OMg2VAg trigonal pyramids. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Mg(1), one V(1), and one Ag(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Mg(1), one V(1), and one Ag(1) atom.
