| Title | Darstellung und Kristallstruktur von K49T1108 Preparation and Crystal Structure of K49T1108  | ||
| Abstract | K49TI 10g was prepared from the elements (molar ratio K:T1 = 1:2) at 700 K. The crystal structure was determined by single crystal X-ray diffraction methods (a = 1728.7(1) pm, Pm 3, Z — 1, R = 0.086). It contains T l12 icosahedra and T l12 truncated tetrahedra (Kasper polyhed-ra). 20 truncated tetrahedra form Tlg4-polyhedra (Sam son polyhedra) by sharing hexagonal faces. These polyhedra are connected by com m on edges. Folded T l3-chains connect the icosa hedra and the Samson polyhedra to a framework. The truncated tetrahedra are occupied by potassium atoms. | ||
