Ag3AsO4 crystallizes in the trigonal R3c space group. Ag(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2) and three equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ag(1) and one As(1) atom to form distorted corner-sharing OAg3As tetrahedra. In the second O site, O(2) is bonded to three equivalent Ag(1) and one As(1) atom to form distorted corner-sharing OAg3As tetrahedra.
Ag3AsO4 crystallizes in the trigonal R3c space group. Ag(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2) and three equivalent O(1) atoms. The Ag(1)-O(2) bond length is 2.45 Å. There are a spread of Ag(1)-O(1) bond distances ranging from 2.28-2.51 Å. As(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. The As(1)-O(2) bond length is 1.70 Å. All As(1)-O(1) bond lengths are 1.71 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ag(1) and one As(1) atom to form distorted corner-sharing OAg3As tetrahedra. In the second O site, O(2) is bonded to three equivalent Ag(1) and one As(1) atom to form distorted corner-sharing OAg3As tetrahedra.
