[SnBi3 ]5-  -A Carbonate Analogue Comprising Exclusively Metal Atoms.


The new [SnBi3 ]5- polyanion is obtained by the reaction of K3 Bi2 with K4 Sn9 or K12 Sn17 in liquid ammonia. The anion is iso(valence)electronic with and structurally analogous to the carbonate ion. Despite the high negative charge of the anion, the Sn-Bi bond lengths range between single and double bonds. Quantum-chemical calculations at a DFT-PBE0/def2… (More)
