Materials Data on Ba4PrDy(Cu3O7)2 by Materials Project
Abstract
Ba4DyPr(Cu3O7)2 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are two 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 2.78–3.00 Å. In the second Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.78–3.07 Å. Dy3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.41 Å) and four longer (2.44 Å) Dy–O bond lengths. Pr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.48 Å) and four longer (2.50 Å) Pr–O bond lengths. There are three inequivalent Cu+2.17+ sites. In the first Cu+2.17+ site, Cu+2.17+ is bonded to five O2- atoms to form corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.96–2.23 Å. In the second Cu+2.17+ site, Cu+2.17+ is bonded to five O2- atoms to form corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.97–2.26 Å. In the third Cu+2.17+ site, Cu+2.17+ ismore »
