The material described by MgVAg3O4 crystallizes in the orthorhombic I222 space group. Mg(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. V(1) is bonded to four equivalent O(1) atoms to form distorted VO4 tetrahedra that share corners with eight equivalent Ag(1)O4 trigonal pyramids. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent O(1) atoms to form distorted AgO4 trigonal pyramids that share corners with four equivalent V(1)O4 tetrahedra and corners with four equivalent Ag(1)O4 trigonal pyramids. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded in a 5-coordinate geometry to one Mg(1), one V(1), one Ag(2), and two equivalent Ag(1) atoms. is represented by the CIF file [CIF]
