Materials Data on BaPrCu2O5 by Materials Project
Abstract
BaPrCu2O5 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–2.98 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share faces with two equivalent BaO12 cuboctahedra and faces with eight CuO5 square pyramids. There are a spread of Ba–O bond distances ranging from 2.85–3.06 Å. In the third Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.78–2.92 Å. There are three inequivalent Pr4+ sites. In the first Pr4+ site, Pr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.48–2.55 Å. In the second Pr4+ site, Pr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.48–2.53 Å. In the third Pr4+ site, Pr4+ is bonded in a 8-coordinate geometry to eight O2- atoms. Theremore »
