Cu5H4(O4Cl)2(H2O)2 crystallizes in the triclinic P-1 space group. The structure consists of two water molecules inside a Cu5H4(O4Cl)2 framework. In the Cu5H4(O4Cl)2 framework, there are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted square co-planar geometry to one O(1), one O(2), two equivalent O(3), and one Cl(1) atom. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. In the third Cu site, Cu(3) is bonded in a distorted square co-planar geometry to two equivalent O(1), two equivalent O(4), and two equivalent Cl(1) atoms. In the fourth Cu site, Cu(4) is bonded in a distorted square co-planar geometry to two equivalent O(2), two equivalent O(4), and two equivalent Cl(1) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one O(1) and one Cl(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one O(2) and one Cl(1) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Cu(1), one Cu(2), one Cu(3), and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cu(1), one Cu(2), one Cu(4), and one H(2) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to two equivalent Cu(1) atoms. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Cu(2), one Cu(3), and one Cu(4) atom. Cl(1) is bonded in a 5-coordinate geometry to one Cu(1), one Cu(3), one Cu(4), one H(1), and one H(2) atom.
