Materials Data on CaEu2(CuO3)2 by Materials Project
CaEu2(CuO3)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.84 Å. Eu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Eu–O bond distances ranging from 2.38–2.59 Å. Cu2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.90–1.94 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Eu3+ and one Cu2+ atom to form a mixture of distorted edge and corner-sharing OEu4Cu trigonal bipyramids. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ca2+, one Eu3+, and two equivalent Cu2+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ca2+, two equivalent Eu3+, and one Cu2+ atom.
