Abstract

Dy2(BiO2)7 crystallizes in the monoclinic Cm space group. The structure is two-dimensional and consists of one Dy2(BiO2)7 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Dy–O bond distances ranging from 2.38–2.62 Å. In the second Dy3+ site, Dy3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Dy–O bond distances ranging from 2.28–2.57 Å. There are seven inequivalent Bi+3.14+ sites. In the first Bi+3.14+ site, Bi+3.14+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing BiO5 square pyramids. There are one shorter (2.13 Å) and four longer (2.41 Å) Bi–O bond lengths. In the second Bi+3.14+ site, Bi+3.14+ is bonded to five O2- atoms to form distorted corner-sharing BiO5 trigonal bipyramids. There are a spread of Bi–O bond distances ranging from 2.18–2.56 Å. In the third Bi+3.14+ site, Bi+3.14+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Bi–O bond distances ranging from 2.19–2.23 Å. In the fourth Bi+3.14+ site, Bi+3.14+ is bonded inmore »« less
