Abstract

TbBaMn2O5 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with four equivalent BaO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, faces with four equivalent MnO5 square pyramids, and faces with four equivalent MnO5 trigonal bipyramids. There are four shorter (2.82 Å) and eight longer (3.21 Å) Ba–O bond lengths. Tb4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Tb–O bond lengths are 2.44 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with five equivalent MnO5 square pyramids and faces with four equivalent BaO12 cuboctahedra. There are one shorter (2.07 Å) and four longer (2.10 Å) Mn–O bond lengths. In the second Mn2+ site, Mn2+ is bonded to five O2- atoms to form MnO5 square pyramids that share corners with five equivalent MnO5 trigonal bipyramids and faces with four equivalent BaO12 cuboctahedra. There are four shorter (1.97 Å) and one longer (2.10 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2-more »« less
