Abstract

A new bismuth tellurium oxychloride was obtained by reaction of BiOCl and TeO2 in air. According to energy dispersive X-ray spectroscopy and neutron powder diffraction refinement the composition of the substance was determined as Bi0.87Te2O4.9Cl0.87. The new compound crystallizes in the trigonal system space group R (3) over bar (#148), Z = 6, a = 4.10793(4), c = 31.1273(4)angstrom, chi(2)=3.20, wR(P) = 0.0369. Bi0.87Te2O4.9Cl0.87 has a new type of layered structure constructed by Bi-Te-O layers separated by chloride ions. The Te atoms in Bi0.87Te2O4.9Cl0.87 show an unusual umbrella-like environment. A comparison with known related structures has been made. (C) 2007 Elsevier Inc. All rights reserved.
