CuCdAsHO5 crystallizes in the orthorhombic Pnma space group. Cu(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form CuO6 octahedra that share corners with four equivalent As(1)O4 tetrahedra and edges with two equivalent Cu(1)O6 octahedra. Cd(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), and four equivalent O(1) atoms. As(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form AsO4 tetrahedra that share corners with four equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-57°. H(1) is bonded in a distorted linear geometry to one O(2) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Cu(1), one Cd(1), and one H(1) atom. In the second O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Cu(1), two equivalent Cd(1), and one As(1) atom. In the third O site, O(2) is bonded in a distorted T-shaped geometry to one Cd(1), one As(1), and one H(1) atom. In the fourth O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Cu(1), one Cd(1), and one As(1) atom.
