Ag2CaV4O12 crystallizes in the tetragonal P4/nbm space group. Ca(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with four equivalent Ag(1)O6 octahedra and corners with two equivalent V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 54-71°. Ag(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form AgO6 octahedra that share corners with eight equivalent V(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ca(1), one V(1), and one Ag(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent V(1) and one Ag(1) atom.
