Abstract

Abstract An outline of the structure of a continuous solid-solution series Bi 2− x La x WO 6 with x = 0.4–1.1 (space group P2/c and Z = 8) has been determined from a lattice imaging method of electron microscopy. A high-resolution lattice image of Bi 1.4La 0.6WO 6 selected as representative of the series showed that the structure consists of a regular stacking of Bi 1.4La 0.6O 2 layers interleaved with WO 4 layers. A structural model of Bi 2− x La x WO 6 was proposed and atomic coordinates were estimated on the basis of the model. The structural relations between Bi 2− x La x WO 6 and Bi 2WO 6 were discussed.
