[en] The authors attempt to produce several new layered perovskite-like compounds of the composition Bi₂AB₂O₉ and to study their crystallographic and physicochemical properties. The authors examine the scope for producing new bismuth-containing layered perovskite-like compounds by heterovalent substitution of ions in the starting compounds Bi₃TiNbO₉ and Bi₃TiTaO₉. Preliminary sintering was carried out and the compounds were analyzed with the help of a DRON-2 x-ray diffractometer. It was found that in all cases layered bismuth compounds are formed. The results of the measurements of the diffraction patterns of Bi₂Pb₁/₃Bi₂/₃Ti₄/₃W₂/₃O₉ are presented in a table
