AgCu2H(SO5)2 crystallizes in the monoclinic C2/m space group. Ag(1) is bonded to two equivalent O(3), two equivalent O(4), and four equivalent O(2) atoms to form distorted AgO8 hexagonal bipyramids that share corners with four equivalent S(1)O4 tetrahedra, edges with four equivalent Cu(1)O6 octahedra, and edges with two equivalent S(1)O4 tetrahedra. Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted CuO6 octahedra that share corners with four equivalent S(1)O4 tetrahedra, edges with two equivalent Ag(1)O8 hexagonal bipyramids, and edges with two equivalent Cu(1)O6 octahedra. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. S(1) is bonded to one O(3), one O(4), and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with two equivalent Ag(1)O8 hexagonal bipyramids, corners with four equivalent Cu(1)O6 octahedra, and  an edgeedge with one Ag(1)O8 hexagonal bipyramid. The corner-sharing octahedral tilt angles range from 42-54°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Ag(1), one Cu(1), and one S(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Ag(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Ag(1), two equivalent Cu(1), and one S(1) atom.
