Abstract

Three new bismuth oxyhalides, Pb-x,Bi2-xCuxO2X2 (X=Cl,x approximate to 0.35-0.70; X=Br,x approximate to 0.35-0.65; X=I,x approximate to 0.35-0.55) have been predicted and synthesized from PbO, BiOX and CuX. All three compounds adopt a very deficient LaOAgS (stuffed PbFCl) structure. Atomic parameters have been determined for Pb0.6Bi1.4Cu0.6O2Cl2 and Pb0.6Bi1.4Cu0.6O2Br2 (P4/nmm, Z= 1) as well as for a structurally and compositionally related Pb0.6Bi1.4Cs0.6O2Br2 (I4/mmm, Z=2). Comparison of these structural data with bond distances and angles in related Pb(0.6)Bi(1.4)Q(0.6)O(2)X(2) oxyhalides(Q = Rb, Cs, Tl; X = Cl, Br) reveals that replacement of CsCl-like [Q(0.6)X(2)] layers by anti-fluorite-like [Cu0.6X2] has a small effect on the Pb0.6Bi1.4-O and Pb0.6Bi1.4-X distances and a larger one on bond angles. We predict existence of isostructural compounds among multinary oxyhalides of bismuth and fluorohalides of lead. It is also likely that more complicated structures involving [CuxX2] layers can be realized. (c) 2005 Published by Elsevier B.V.
