Materials Data on Ba2ErCuNi2O7 by Materials Project

Kristin Persson
Ba2ErNi2CuO7 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. 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. Er3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.40 Å) and four longer (2.42 Å) Er–O bond lengths. Ni3+ is bonded to five O2- atoms to form corner-sharing NiO5 square pyramids....
