| Abstract: | The use of ionic liquids (CnC1Im)BF4] with long alkyl chains (n=10, 12) in the ionothermal treatment of Na2HgTe2] 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 π‐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 (σ) aromaticity. As a result of their lamellar nature, the compounds are promising candidates for the formation of sheets containing chalcogenidometalate anions. |
