Title: The crystal structure of a new bismuth tellurium oxychloride Bi{sub 0.87}Te{sub 2}O{sub 4.9}Cl{sub 0.87} from neutron powder diffraction data

Abstract

A new bismuth tellurium oxychloride was obtained by reaction of BiOCl and TeO{sub 2} in air. According to energy dispersive X-ray spectroscopy and neutron powder diffraction refinement the composition of the substance was determined as Bi{sub 0.87}Te{sub 2}O{sub 4.9}Cl{sub 0.87}. The new compound crystallizes in the trigonal system space group R 3-bar (no. 148), Z=6, a=4.10793(4), c=31.1273(4) A, {chi} {sup 2}=3.20, wR {sub p}=0.0369. Bi{sub 0.87}Te{sub 2}O{sub 4.9}Cl{sub 0.87} has a new type of layered structure constructed by Bi-Te-O layers separated by chloride ions. The Te atoms in Bi{sub 0.87}Te{sub 2}O{sub 4.9}Cl{sub 0.87} show an unusual umbrella-like environment. A comparison with known related structures has been made. - Graphical abstract: A new bismuth tellurium oxychloride Bi{sub 0.87}Te{sub 2}O{sub 4.9}Cl{sub 0.87} has been synthesized. The compound has a new type of layered structure.
