Materials Data on Y2Cu2O5 by Materials Project
Abstract
Y2Cu2O5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.27–2.57 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.84–2.01 Å. In the second Cu2+ site, Cu2+ is bonded in a T-shaped geometry to three O2- atoms. There is two shorter (1.85 Å) and one longer (2.06 Å) Cu–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Y3+ and three Cu2+ atoms to form OY2Cu3 trigonal bipyramids that share corners with six OY3Cu tetrahedra, corners with two equivalent OY2Cu3 trigonal bipyramids, and edges with six OY3Cu tetrahedra. In the second O2- site, O2- is bonded to three equivalent Y3+ and one Cu2+ atom to form OY3Cu tetrahedra that share corners with ten OY3Cu tetrahedra, a cornercorner with one OY2Cu3 trigonal bipyramid, edges with three OY3Cu tetrahedra, and edges with two equivalent OY2Cu3 trigonal bipyramids. In the third O2- site, O2- ismore »
