Abstract:

The new compounds CeNb7O12 and PrNb7O12, isostructural with LaNb7O12, have been synthesized and characterized by x-ray diffraction. The structures of the LnNb(7)O(12) (Ln = La, Ce, Pr) compounds have space group P2(1)/c (Z = 4), with lattice parameters a = 10.764(2), 10.743(2), 10.738(4) angstrom; b = 9.192(2), 9.146(2), 9.137(3) angstrom; c = 10.313(2), 10.304(2), 10.303(3) angstrom; and beta = 104.25(2)degrees, 104.31(2)degrees, and 104.21(3)degrees, respectively. The reduction in the lattice parameters of LnNb(7)O(12) in going from La to Pr correlates with the ionic radii of Ln: r(La3+) > r(Ce3+) > r(Pr3+). In the Nd(Sm)-Nb-O systems, phases of stoichiometry LnNb(7)O(12) have not been obtained.
