The compound described by CrHg(PbO3)2 crystallizes in the triclinic P-1 space group. Cr(1) is bonded in a tetrahedral geometry to one O(3), one O(4), one O(5), and one O(6) atom. Hg(1) is bonded in a linear geometry to one O(1) and one O(2) atom. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to one O(2), one O(4), and two equivalent O(1) atoms. In the second Pb site, Pb(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Hg(1), one Pb(2), and two equivalent Pb(1) atoms to form edge-sharing OHgPb3 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Hg(1), one Pb(1), and one Pb(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cr(1) and one Pb(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Cr(1) and one Pb(1) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one Cr(1) and one Pb(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Cr(1) and one Pb(2) atom. is represented by the CIF card [CIF]
