Materials Data on Cd(CuO2)2 by Materials Project
Cd(CuO2)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Cu3+ sites. In the first Cu3+ site, Cu3+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.85 Å) and two longer (1.86 Å) Cu–O bond length. In the second Cu3+ site, Cu3+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.85 Å) and two longer (1.86 Å) Cu–O bond length. Cd2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cd–O bond distances ranging from 2.42–2.49 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two Cu3+ and two equivalent Cd2+ atoms to form a mixture of distorted edge and corner-sharing OCd2Cu2 tetrahedra. In the second O2- site, O2- is bonded to two Cu3+ and two equivalent Cd2+ atoms to form a mixture of distorted edge and corner-sharing OCd2Cu2 tetrahedra.
