The crystal structure described by Pb2CO3F2 crystallizes in the orthorhombic Pbcn space group. Pb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent F(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one C(1) atom. F(1) is bonded to four equivalent Pb(1) atoms to form a mixture of distorted edge and corner-sharing FPb4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
