Abstract

SmBaCuFeO5 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.82 Å) and four longer (2.93 Å) Ba–O bond lengths. Sm3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.41 Å) and four longer (2.51 Å) Sm–O bond lengths. Fe3+ is bonded to five O2- atoms to form distorted FeO5 trigonal bipyramids that share a cornercorner with one CuO5 square pyramid and corners with four equivalent FeO5 trigonal bipyramids. There is one shorter (1.87 Å) and four longer (2.04 Å) Fe–O bond length. Cu2+ is bonded to five O2- atoms to form CuO5 square pyramids that share corners with four equivalent CuO5 square pyramids and a cornercorner with one FeO5 trigonal bipyramid. There are four shorter (1.97 Å) and one longer (2.48 Å) Cu–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Sm3+ and two equivalent Fe3+ atoms to form a mixture of distorted edge and corner-sharing OSm2Fe2 tetrahedra. In the second O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Ba2+,more »« less
