Abstract

Eu2Ag2O5 is Aluminum carbonitride-like structured and crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. Eu3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Eu–O bond distances ranging from 2.24–2.51 Å. There are two inequivalent Ag2+ sites. In the first Ag2+ site, Ag2+ is bonded to six O2- atoms to form AgO6 octahedra that share corners with four equivalent AgO6 octahedra and corners with two equivalent AgO4 tetrahedra. The corner-sharing octahedral tilt angles are 31°. There are two shorter (2.13 Å) and four longer (2.16 Å) Ag–O bond lengths. In the second Ag2+ site, Ag2+ is bonded to four O2- atoms to form AgO4 tetrahedra that share corners with two equivalent AgO6 octahedra and corners with two equivalent AgO4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Ag–O bond distances ranging from 2.20–2.38 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted see-saw-like geometry to two equivalent Eu3+ and two equivalent Ag2+ atoms. In the second O2- site, O2- is bonded to two equivalent Eu3+ and two Ag2+ atoms to form distorted corner-sharing OEu2Ag2 tetrahedra. In themore »« less
