The crystal structure described by WFe2Pb3O9 crystallizes in the trigonal P-3m1 space group. W(1) is bonded to six equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and faces with two equivalent Pb(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. Fe(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form FeO6 octahedra that share corners with three equivalent W(1)O6 octahedra, corners with three equivalent Fe(1)O6 octahedra, and faces with three equivalent Pb(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-1°. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form PbO12 cuboctahedra that share corners with six equivalent Pb(1)O12 cuboctahedra, faces with two equivalent W(1)O6 octahedra, and faces with six equivalent Fe(1)O6 octahedra. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent Fe(1), two equivalent Pb(1), and two equivalent Pb(2) atoms. In the second O site, O(2) is bonded in a linear geometry to one W(1), one Fe(1), and one Pb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
