Anionische Antimon(III)-Fluorokomplexe mit protonierten Azakronenethern als Gegenionen. Strukturen und Mößbauerspektren von [H2cyclam]2[Sb4F16] · 2 H2O, [H4cyclam][Sb2F10] · 2 HF und [H4(tetramethyl)cyclam]2[Sb4F15][HF2][F]4 (cyclam = 1,4,7,11-Tetraazacyclotetradecan)

Anionic Antimony(III) Fluoro Complexes with protonated Azacrownethers as Counterions. Crystal Structures and Mößbauer Spectra of H₂cyclam]₂Sb₄F₁₆] · 2H₂O, H₄cyclam]Sb₂F₁₀] · 2 HF, and H₄(tetramethyl)cyclam]₂Sb₄F₁₅]HF₂]F]₄ (cyclam = 1,4,7,11-Tetraazacyclotetradecane) The title compounds are formed by reaction of SbF₃ with the respective azacrownether. H₂cyclam]₂Sb₄F₁₆] · 2 H₂O contains tetrameric anions which weakly associate to chains. The H₂cyclam]²⁺ ions possess an unusual conformation due to intramolecular hydrogen bonds. H₄cyclam]Sb₂F₁₀] · 2HF contains the dimeric hitherto unknown Sb₂F₁₀]^4? ion; two HF molecules are attached to it by hydrogen bonds. The structure of H₄(tetramethyl)cyclam]₂Sb₄F₁₅]HF₂]F]₄ is made up of the two dimensional polymeric HSb₄F₁₇]^4? anion. The tetra-protonated tetramethylcyclam ions form host-guest complexes with fluoride ions.
