Abstract

Sm4Fe3Co(AsO)4 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. there are four inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four O2- atoms. All Sm–As bond lengths are 3.36 Å. All Sm–O bond lengths are 2.31 Å. In the second Sm3+ site, Sm3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four O2- atoms. All Sm–As bond lengths are 3.35 Å. All Sm–O bond lengths are 2.31 Å. In the third Sm3+ site, Sm3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four O2- atoms. All Sm–As bond lengths are 3.36 Å. All Sm–O bond lengths are 2.31 Å. In the fourth Sm3+ site, Sm3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four O2- atoms. All Sm–As bond lengths are 3.35 Å. All Sm–O bond lengths are 2.31 Å. There are two inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to four equivalent As3- atoms to form a mixture of corner and edge-sharing FeAs4 tetrahedra.
