Materials Data on LiBi3(IO2)2 by Materials Project

Abstract

LiBi3(O2I)2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Li1+ is bonded in a distorted square co-planar geometry to four equivalent O2- atoms. All Li–O bond lengths are 2.11 Å. There are three inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four I1- atoms. All Bi–O bond lengths are 2.28 Å. There are two shorter (3.60 Å) and two longer (3.66 Å) Bi–I bond lengths. In the second Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four I1- atoms. All Bi–O bond lengths are 2.29 Å. There are two shorter (3.56 Å) and two longer (3.62 Å) Bi–I bond lengths. In the third Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four I1- atoms. All Bi–O bond lengths are 2.30 Å. There are two shorter (3.54 Å) and two longer (3.60 Å) Bi–I bond lengths. O2- is bonded to one Li1+ and three Bi3+ atoms to form a mixture of distorted edge and corner-sharing OLiBi3 tetrahedra. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 6-coordinate geometry to six Bi3+ atoms. In the second I1- site, I1- is bonded in a 6-coordinate geometry to six Bi3+ atoms.
