Abstract
Single-crystal X-ray structure determinations of Ce(4)I(6)CN and disordered Ce(6)I(9)C(2)N phases are described together with electron-microscopy studies of Ce(6)I(9)C(2)N and Y(6)I(9)C(2)N. Ce(4-) I(6)CN crystallizes in the tetragonal space group P4(2)/mnm with a = 13.877(2) angstrom, c = 9.665(2) angstrom. Compounds beta'-Ce(6)I(9)C(2)N and beta ''-Ce(6)I(9)C(2)N crystallize in space group P6/m with a = 41.774(6) angstrom, c = 13.719(3) angstrom and a = 20.958(3) angstrom, c = 13.793(3) angstrom, respectively. The main structural feature of these compounds are rods of RE(6)C(2) octahedra and RE(4)N tetrahedra (RE = lanthanide) interconnected in different sequences. These rods are linked into Kagome-type frameworks with additional rods located in the centres of the hexagonal channels. The disorder patterns for these additional rods can be rationalized in terms of nearest-neighbour interactions.
