Abstract

An aminocryptand host enforces approach of encapsulated Tl(I) ions to just within 4.4 Å; despite this relatively large separation, strong Tl(I)⋯Tl(I) interaction is observed and the aromatic proton of the bridging link exhibits a large through-space coupling to the pair of equivalent Tl nuclei.
