Abstract

Ho2Cu2O5 is Spinel-like structured and crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing HoO6 octahedra. The corner-sharing octahedra tilt angles range from 22–64°. There are a spread of Ho–O bond distances ranging from 2.23–2.31 Å. In the second Ho3+ site, Ho3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing HoO6 octahedra. The corner-sharing octahedra tilt angles range from 22–64°. There are a spread of Ho–O bond distances ranging from 2.22–2.31 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.94–2.02 Å. In the second Cu2+ site, Cu2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.95–2.01 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to three Ho3+ and one Cu2+ atom to form distorted OHo3Cu tetrahedra that share corners withmore »« less
