| Popis: |
The use of ionic liquids (C(n)C(1)Im)[BF4] with long alkyl chains (n=10,12) in the ionothermal treatment of Na-2[HgTe2] led to lamellar crystal structures with molecular macrocyclic anions [Hg8Te16](8-) (1), the heaviest known topological relative of porphyrin. [Hg8Te16](8-) differs from porphyrin by the absence of an electronic pi-system, which prevents a global aromaticity. Quantum chemical studies reveal instead small ring currents in the pyrrole-type five-membered rings that indicate weak local (sigma) aromaticity. As a result of their lamellar nature, the compounds are promising candidates for the formation of sheets containing chalcogenidometalate anions. |
