Pb(CO3)2 crystallizes in the orthorhombic Pnma space group. The structure consists of four hydrogen peroxide molecules inside a PbC2O4 framework. In the PbC2O4 framework, Pb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to one Pb(1) and one C(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one C(1) atom.

In the PbC2O4 framework, Pb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Pb(1)-O(2) bond lengths are 2.48 Å. There are two shorter (2.48 Å) and two longer (2.84 Å) Pb(1)-O(1) bond lengths. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.28 Å. The C(1)-O(2) bond length is 1.26 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to one Pb(1) and one C(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one C(1) atom.
