Reversible dynamic isomerism change in the solid state, from Bi4I16clusters to BiI4 1D chains in l-cystine based hybrids: templating effect of cations in iodobismuthate network formation

Abstract

The dehydration of a iodobismuthate hybrid built up from Bi₄I₁₆clusters and protonated L-cystine molecules involves an unprecedented reversible dynamic structural change in the solid state leading to 1D BiI₄ chains and 1D helical molecular chains, highlighting the templating effect of cations in the formation of iodobismuthate network.
