FeCo(BiO3)2 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. Fe3+ is bonded in a 5-coordinate geometry to five O2- atoms. There is one shorter (1.82 Å) and four longer (2.04 Å) Fe–O bond length. Co3+ is bonded in a 5-coordinate geometry to five O2- atoms. There is one shorter (1.76 Å) and four longer (2.03 Å) Co–O bond length. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.30 Å) and four longer (2.84 Å) Bi–O bond lengths. In the second Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.30 Å) and four longer (2.85 Å) Bi–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Co3+ and four equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Fe3+ and four equivalent Bi3+ atoms. In the third O2- site, O2- is bonded to two equivalent Co3+ and two equivalent Bi3+ atoms to form a mixture of distorted corner and edge-sharing OCo2Bi2 tetrahedra. In the fourth O2- site, O2- is bonded to two equivalent Fe3+ and two equivalent Bi3+ atoms to form a mixture of distorted corner and edge-sharing OFe2Bi2 tetrahedra.
