Abstract

The existence of a complete series of mixed crystals Bi2O2(TexSe1-x), 0 les s than or equal to x less than or equal to 1 in the pseudobinary system Bi2 O2Se/Bi2O2Te has been detected by solid state reactions. The crystal structure of the ternary phase Bi2O2Se was refined on the basis of single crystal measurements. The crystallographic data for Bi2O2Te and for compositions of the mixed crystals were obtained using powder x-ray mea surements: Bi2O2Se I4/mmm (No. 139); Z = 2; a = 3.887(1). c = 12.164(2) Angstrom, Bi2O2Te0,5Se0,5 I4/mmm (No. 139); Z = 2; a = 3.934(1), c = 12.454(2) Angstr om, Bi2O2Te I4/mmm (No. 139); Z = 2; a = 3.983(1), c = 12.699(2) Angstrom.
