The crystal structure of K(5)PrLi(2)F(10) is isotypic with those of other K(5)RELi(2)F(10) compounds (RE = Eu, Nd). The lanthanoid ions are isolated in K(5)PrLi(2)F(10), with a mean separation between the Pr ions of 7.356 Å. It classifies this crystal as a so-called self-activated material containing lanthanoid ions within the matrix. Except for two K(+) and two F(-) ions, all atoms are located on sites with m symmetry. In the structure, distorted PrF(8) dodeca-hedra and two different LiF(4) tet ...[more]
