The crystal structure described by Pb2OF2 crystallizes in the orthorhombic Pmm2 space group. There are four inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one O(2), two equivalent F(1), and two equivalent F(2) atoms. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent F(1), and two equivalent F(2) atoms. In the third Pb site, Pb(3) is bonded in a 5-coordinate geometry to one O(4), two equivalent F(1), and two equivalent F(2) atoms. In the fourth Pb site, Pb(4) is bonded to one O(3), two equivalent F(1), and two equivalent F(2) atoms to form corner-sharing PbOF4 square pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Pb(2) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent Pb(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Pb(4) atoms. In the fourth O site, O(4) is bonded to two equivalent Pb(2) and two equivalent Pb(3) atoms to form distorted OPb4 tetrahedra that share corners with eight equivalent F(2)Pb4 tetrahedra and edges with four equivalent F(1)Pb4 tetrahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded to one Pb(1), one Pb(2), one Pb(3), and one Pb(4) atom to form FPb4 tetrahedra that share corners with four equivalent F(1)Pb4 tetrahedra, corners with four equivalent F(2)Pb4 tetrahedra,  an edgeedge with one O(4)Pb4 tetrahedra, and edges with two equivalent F(2)Pb4 tetrahedra. In the second F site, F(2) is bonded to one Pb(1), one Pb(2), one Pb(3), and one Pb(4) atom to form distorted FPb4 tetrahedra that share corners with two equivalent O(4)Pb4 tetrahedra, corners with four equivalent F(1)Pb4 tetrahedra, corners with four equivalent F(2)Pb4 tetrahedra, and edges with two equivalent F(1)Pb4 tetrahedra. is represented by the CIF card [CIF]
