AgAlO3 crystallizes in the hexagonal P6_3cm space group. Ag(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form AgO5 trigonal bipyramids that share corners with two equivalent Al(2)O4 tetrahedra and corners with six equivalent Ag(1)O5 trigonal bipyramids. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 7-coordinate geometry to one O(1), three equivalent O(3), and three equivalent O(4) atoms. In the second Al site, Al(2) is bonded to one O(2) and three equivalent O(4) atoms to form AlO4 tetrahedra that share corners with six equivalent Ag(1)O5 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ag(1) and one Al(1) atom to form corner-sharing OAlAg3 tetrahedra. In the second O site, O(2) is bonded to three equivalent Ag(1) and one Al(2) atom to form corner-sharing OAlAg3 tetrahedra. In the third O site, O(3) is bonded in a trigonal planar geometry to one Ag(1) and two equivalent Al(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ag(1), one Al(2), and two equivalent Al(1) atoms.
