CaAgBiO5 crystallizes in the monoclinic P2_1/c space group. Ca(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms. Ag(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(5) atom. Bi(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form distorted edge-sharing BiO6 pentagonal pyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ca(1), one Ag(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Ca(1), one Ag(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a T-shaped geometry to one Ca(1), one Ag(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded to two equivalent Ca(1) and two equivalent Bi(1) atoms to form edge-sharing OCa2Bi2 tetrahedra. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Ca(1), one Ag(1), and one Bi(1) atom.
