The structure described by Cr3Pb5O12Cl crystallizes in the hexagonal P6_3/m space group. Cr(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(3) atoms. In the second Pb site, Pb(2) is bonded in a 5-coordinate geometry to one O(3), four equivalent O(2), and two equivalent Cl(1) atoms. There are three inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one Cr(1), one Pb(2), and two equivalent Pb(1) atoms. In the second O site, O(1) is bonded in a distorted single-bond geometry to one Cr(1) and two equivalent Pb(1) atoms. In the third O site, O(2) is bonded in a distorted single-bond geometry to one Cr(1) and two equivalent Pb(2) atoms. Cl(1) is bonded to six equivalent Pb(2) atoms to form face-sharing ClPb6 octahedra. is represented by the CIF file [CIF]
