Ba2AuTl7: an intermetallic compound with a novel condensed structure.
In this novel motif, thallium and gold atoms define a complex three-dimensional [AuTl(7)] polyanion in which the barium atoms fill pentagonal cages that are part of highly condensed infinite channels. Relativistic effects appear to be significant in the short Au-Tl and Tl-Tl distances and the bonding by the more electronegative gold.
