Modulated structures in oxidised cerium niobates
Three previously reported oxidized cerium niobate phases CeNbO4+x(x=0.08, 0.25, and 0.33) have been synthesized and characterized by X-ray powder and electron diffraction. All three phases display structures which are modulated variants of a parent fergusonite-type CeIIINbO4structure (I2/a,a=5.5342 (2) Åb=11.4016(6) Å,c=5.1583 (3) Å,β=94.600(5)°). Thex=0.08 phase with parent unit cell (I2/a,a=5.3029(8) Å,b=11.483(2) Å,c=5.2515(8) Å,β=91.32(2)°) is a two-dimensional, incommensurately modulated...[Show more]
