The material described by AgCu4(AsO4)3 crystallizes in the monoclinic C2/c space group. Ag(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(5) atoms. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 6-coordinate geometry to one O(1), one O(3), one O(4), one O(5), and two equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(3) and two equivalent O(6) atoms. In the third Cu site, Cu(3) is bonded in a distorted square co-planar geometry to two equivalent O(4) and two equivalent O(6) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a tetrahedral geometry to one O(2), one O(3), one O(5), and one O(6) atom. In the second As site, As(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Ag(1), one Cu(1), and one As(2) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Cu(1) and one As(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ag(1), one Cu(1), one Cu(2), and one As(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Cu(1), one Cu(3), and one As(2) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Ag(1), one Cu(1), and one As(1) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one Cu(2), one Cu(3), and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
