The structure described by Sr2FeCu(PbO3)2 crystallizes in the orthorhombic Pmna space group. Sr(1) is bonded in a 9-coordinate geometry to one O(3), four equivalent O(1), and four equivalent O(2) atoms. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles are 4°. Cu(1) is bonded in a linear geometry to two equivalent O(3) atoms. Pb(1) is bonded in a distorted L-shaped geometry to one O(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Sr(1) and two equivalent Fe(1) atoms to form a mixture of distorted edge, face, and corner-sharing OSr4Fe2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Fe(1), and one Pb(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one Cu(1), and one Pb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
