description | Single crystals of octaiodine henacosarsenic pentacosagermanium were grown by chemical transport reactions. The structure is isotypic with the analogous clathrates-I. In this structure, the statistically occupied clathrand atoms (As,Ge)(46) form bonds in a distorted tetrahedral coordination and their arrangement can define two polyhedra of different sizes; one is an (As,Ge)(20) pentagonal dodecahedron, and the other is an (As,Ge)(24) tetrakaidecahedron. The guest atom (iodine) resides inside these polyhedra with site symmetry m3 (Wyckoff position 2a) and [Image: see text]2m (Wyckoff position 6d), respectively. |
