PbH2O7Cl2 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four PbH2O7Cl2 clusters. Pb(1) is bonded in a 3-coordinate geometry to one O(3) and two equivalent O(4) atoms. H(1) is bonded in a single-bond geometry to one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Cl(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Cl(1) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one Pb(1) and two equivalent H(1) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Pb(1) and one Cl(1) atom. Cl(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(4) atom.
