The material structure described by FePbBiPO7 crystallizes in the monoclinic Cm space group. Fe(1) is bonded to one O(1), one O(2), two equivalent O(5), and two equivalent O(6) atoms to form distorted FeO6 pentagonal pyramids that share corners with two equivalent Fe(1)O6 pentagonal pyramids and corners with two equivalent P(1)O4 tetrahedra. Pb(1) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(1), two equivalent O(3), and two equivalent O(6) atoms. Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(5), two equivalent O(2), and two equivalent O(4) atoms. P(1) is bonded to one O(3), one O(4), and two equivalent O(6) atoms to form PO4 tetrahedra that share corners with two equivalent Fe(1)O6 pentagonal pyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Fe(1), two equivalent Pb(1), and one Bi(1) atom to form distorted OFeBiPb2 tetrahedra that share  a cornercorner with one O(2)FeBi2Pb tetrahedra, corners with two equivalent O(1)FeBiPb2 tetrahedra, and edges with two equivalent O(2)FeBi2Pb tetrahedra. In the second O site, O(2) is bonded to one Fe(1), one Pb(1), and two equivalent Bi(1) atoms to form OFeBi2Pb tetrahedra that share  a cornercorner with one O(1)FeBiPb2 tetrahedra, corners with two equivalent O(2)FeBi2Pb tetrahedra, and edges with two equivalent O(1)FeBiPb2 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to two equivalent Bi(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Fe(1) and one Bi(1) atom. In the sixth O site, O(6) is bonded in a 2-coordinate geometry to one Fe(1), one Pb(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
