VAgSeO5 crystallizes in the orthorhombic Pbcm space group. V(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. Ag(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Se(1) is bonded in a distorted T-shaped geometry to one O(2) and two equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one Ag(1), and one Se(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ag(1) and one Se(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms.
