Materials Data on Er(CuO2)2 by Materials Project

Er(CuO2)2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Er3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.36 Å) and four longer (2.38 Å) Er–O bond lengths. Cu+2.50+ is bonded in a square co-planar geometry to four equivalent O2- atoms. There is two shorter (1.89 Å) and two longer (1.92 Å) Cu–O bond length. O2- is bonded to two equivalent Er3+ and two equivalent Cu+2.50+ atoms to form a mixture of distorted edge and corner-sharing OEr2Cu2 tetrahedra.
