Abstract
The compound K14Cd9Tl21 has been prepared by fusion of the elements in a tantalum reactor followed by slow cooling at the rate of 6 per hour to enable crystal growth. The X-ray crystal structure (hexagonal, P62m; a = 9.884(3),c= 17.173(5) Å; Z= 2) was refined to reliability factors of R1 = 5.09, wR2 = 11.64%. The anionic substructure contains both isolated clusters of Tl11/7- and a layered network based on Cd5Tl2 pentagonal bipyramids. The structure electron count relationship for the Tl11/7- cluster was analyzed in detail. The Cd9Tl10/7- layers are found to confer metallic properties to the material, and the bonding within such layers is found to be highly delocalized.
