Materials Data on BaYMnCoO5 by Materials Project
Abstract
YBaMnCoO5 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 CoO5 square pyramids. There are four shorter (2.78 Å) and eight longer (3.16 Å) Ba–O bond lengths. Y3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Y–O bond lengths are 2.43 Å. Mn2+ is bonded to five O2- atoms to form MnO5 square pyramids that share corners with five equivalent CoO5 square pyramids and faces with four equivalent BaO12 cuboctahedra. There are four shorter (1.97 Å) and one longer (2.06 Å) Mn–O bond lengths. Co3+ is bonded to five O2- atoms to form CoO5 square pyramids that share corners with five equivalent MnO5 square pyramids and faces with four equivalent BaO12 cuboctahedra. There are four shorter (2.04 Å) and one longer (2.09 Å) Co–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Ba2+, one Mn2+, and one Co3+ atom to form a mixture ofmore »
