Materials Data on Bi3ClO4 by Materials Project
Bi3O4Cl crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 3-coordinate geometry to three O2- and two equivalent Cl1- atoms. There are a spread of Bi–O bond distances ranging from 2.13–2.16 Å. There are one shorter (3.30 Å) and one longer (3.32 Å) Bi–Cl bond lengths. In the second Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.25–2.92 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Bi3+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to four Bi3+ atoms. Cl1- is bonded in a 4-coordinate geometry to four equivalent Bi3+ atoms.
