Materials Data on Lu(CuO2)2 by Materials Project
Lu(CuO2)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Lu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Lu–O bond distances ranging from 2.31–2.34 Å. There are two inequivalent Cu+2.50+ sites. In the first Cu+2.50+ site, Cu+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.89 Å) and two longer (1.92 Å) Cu–O bond length. In the second Cu+2.50+ site, Cu+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.89 Å) and two longer (1.91 Å) Cu–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Lu3+ and two Cu+2.50+ atoms to form a mixture of distorted edge and corner-sharing OLu2Cu2 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Lu3+ and two Cu+2.50+ atoms to form a mixture of distorted edge and corner-sharing OLu2Cu2 tetrahedra.
