Ag2CrO4 crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form CrO4 tetrahedra that share corners with six equivalent Ag(1)O6 octahedra and corners with four equivalent Ag(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 46-54°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted AgO6 octahedra that share corners with six equivalent Cr(1)O4 tetrahedra, corners with six equivalent Ag(2)O4 tetrahedra, and edges with two equivalent Ag(1)O6 octahedra. In the second Ag site, Ag(2) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form distorted AgO4 tetrahedra that share corners with six equivalent Ag(1)O6 octahedra and corners with four equivalent Cr(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 78°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Cr(1), one Ag(2), and two equivalent Ag(1) atoms to form distorted corner-sharing OCrAg3 tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cr(1), one Ag(2), and two equivalent Ag(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Cr(1), one Ag(1), and one Ag(2) atom.
