Abstract

Eu2Y2O5 crystallizes in the monoclinic P2 space group. The structure is three-dimensional. there are four inequivalent Eu2+ sites. In the first Eu2+ site, Eu2+ is bonded to five O2- atoms to form a mixture of edge and corner-sharing EuO5 trigonal bipyramids. There are a spread of Eu–O bond distances ranging from 2.35–2.46 Å. In the second Eu2+ site, Eu2+ is bonded to five O2- atoms to form a mixture of edge and corner-sharing EuO5 trigonal bipyramids. There are a spread of Eu–O bond distances ranging from 2.35–2.46 Å. In the third Eu2+ site, Eu2+ is bonded to five O2- atoms to form a mixture of edge and corner-sharing EuO5 trigonal bipyramids. There are a spread of Eu–O bond distances ranging from 2.36–2.47 Å.
