Abstract
Y2CuO4 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Y3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are four shorter (2.26 Å) and four longer (2.64 Å) Y–O bond lengths. Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.94 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Y3+ and two equivalent Cu2+ atoms to form distorted OY4Cu2 octahedra that share corners with two equivalent OY4Cu2 octahedra, corners with twelve equivalent OY4 tetrahedra, edges with two equivalent OY4Cu2 octahedra, edges with two equivalent OY4 tetrahedra, and faces with four equivalent OY4Cu2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to four equivalent Y3+ atoms to form OY4 tetrahedra that share corners with twelve equivalent OY4Cu2 octahedra, corners with four equivalent OY4 tetrahedra, edges with two equivalent OY4Cu2 octahedra, and edges with four equivalent OY4 tetrahedra. The corner-sharing octahedra tilt angles range from 12–70°.
