Description
A new compound of composition Bi2.53Li0.29Nb2O9 was synthesized in the course of the search for new materials with high ionic conductivity. Its crystal structure was determined from the neutron diffraction data. The new compound Bi2.53Li0.29Nb2O9 is crystallized in the orthorhombic system, sp. gr. Cmc21, and unit-cell parameters a = 24.849(1) A, b 5.4536(3) A, and c = 5.4619(2) A at T = 290 K (a = 24.843(2) A, b = 5.4456(5) A, and c = 5.4546(5) A at T = 10 K). Within the temperature range 10-870 K, no structural phase transitions were revealed. The atomic coordinates and the thermal factors in the isotropic approximation were refined by the Rietveld method at 290 and 10 K. The data obtained were analyzed based on the calculated local balance of bond strengths
