The material structure described by PbCl2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 7-coordinate geometry to one Cl(1), one Cl(3), two equivalent Cl(2), and three equivalent Cl(4) atoms. In the second Pb site, Pb(2) is bonded in a 5-coordinate geometry to one Cl(4), two equivalent Cl(1), and three equivalent Cl(3) atoms. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted T-shaped geometry to one Pb(1) and two equivalent Pb(2) atoms. In the second Cl site, Cl(2) is bonded in a distorted L-shaped geometry to two equivalent Pb(1) atoms. In the third Cl site, Cl(3) is bonded to one Pb(1) and three equivalent Pb(2) atoms to form a mixture of distorted edge and corner-sharing ClPb4 tetrahedra. In the fourth Cl site, Cl(4) is bonded in a 4-coordinate geometry to one Pb(2) and three equivalent Pb(1) atoms. is represented by the CIF file [CIF]
