VAgCuO4 crystallizes in the orthorhombic Pnma space group. 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 Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-61°. Ag(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted CuO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Cu(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded to one V(1), one Ag(1), and two equivalent Cu(1) atoms to form distorted corner-sharing OVCu2Ag tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to one V(1), two equivalent Ag(1), and two equivalent Cu(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one V(1), one Ag(1), and one Cu(1) atom.
