Abstract

Dy2Cu2O5 is Spinel-like structured and crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing DyO6 octahedra. The corner-sharing octahedra tilt angles range from 21–65°. There are a spread of Dy–O bond distances ranging from 2.24–2.33 Å. In the second Dy3+ site, Dy3+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing DyO6 octahedra. The corner-sharing octahedra tilt angles range from 21–65°. There are a spread of Dy–O bond distances ranging from 2.24–2.32 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 1.95–2.02 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 1.95–2.02 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Dy3+ and two Cu2+ atoms to form ODy2Cu2 trigonal pyramids that share cornersmore »« less
