CaAgAsO5 crystallizes in the orthorhombic P2_12_12_1 space group. Ca(1) is bonded in a 8-coordinate geometry to one O(1), one O(5), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Ag(1) is bonded in a 6-coordinate geometry to one O(3), one O(4), two equivalent O(1), and two equivalent O(5) atoms. As(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Ca(1), two equivalent Ag(1), and one As(1) atom to form distorted corner-sharing OCaAg2As tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ca(1) and one As(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Ca(1), one Ag(1), and one As(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Ca(1), one Ag(1), and one As(1) atom. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to one Ca(1) and two equivalent Ag(1) atoms.
