A new polymorph of Pb2BiVO6 was prepared under ambient conditions and its crystal structure was determined by single crystal X-ray diffraction. This crystal structure is twinned and complementary structural investigations of a powder sample of β-Pb2BiVO6 by TEM diffraction studies confirmed the lattice and incommensurate modulation character.

Byl připraven nový polymorf Pb2BiVO6 za pokojových podmínek a byla určena jeho krystalová struktura metodami rentgenové difrakce. Krystal je nesouměřitelně modulované dvojče, což bylo nezávisle potvrzeno difrakční metodou TEM.
