The compound described by KAg2AsO4 crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Ag(1) is bonded to four equivalent O(1) atoms to form distorted AgO4 trigonal pyramids that share corners with four equivalent As(1)O4 tetrahedra and corners with four equivalent Ag(1)O4 trigonal pyramids. As(1) is bonded to four equivalent O(1) atoms to form AsO4 tetrahedra that share corners with eight equivalent Ag(1)O4 trigonal pyramids. O(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent Ag(1), and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
