Materials Data on Ca(CuO)2 by Materials Project
CaCu2O2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing CaO6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are two shorter (2.27 Å) and four longer (2.67 Å) Ca–O bond lengths. Cu1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.86 Å. O2- is bonded to three equivalent Ca2+ and two equivalent Cu1+ atoms to form a mixture of distorted edge and corner-sharing OCa3Cu2 trigonal bipyramids.
