CuZnAsHO5 crystallizes in the orthorhombic Pnnm space group. 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 As(1)O4 tetrahedra, corners with four equivalent Zn(1)O5 trigonal bipyramids, and edges with two equivalent Cu(1)O6 octahedra. Zn(1) is bonded to one O(2), two equivalent O(3), and two equivalent O(4) atoms to form ZnO5 trigonal bipyramids that share corners with four equivalent Cu(1)O6 octahedra, corners with four equivalent As(1)O4 tetrahedra, and  an edgeedge with one Zn(1)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 57-64°. As(1) is bonded to one O(1), one O(3), and two equivalent O(4) atoms to form AsO4 tetrahedra that share corners with four equivalent Cu(1)O6 octahedra and corners with four equivalent Zn(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 55-67°. H(1) is bonded in a single-bond geometry to one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Cu(1) and one As(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cu(1), one Zn(1), and one H(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Zn(1) 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 Zn(1), and one As(1) atom.
