Résumé

The unsymmetrical hydrazonobis(acylhydrazone) ligand L exists in solution as a mixture of isomers but complexes to Hg(II) with a major conformational change, affording a mixture of parallel and antiparallel binuclear double helicates. On crystallisation of the triflate salt, however, the antiparallel strand isomer is selected presumably due to the optimisation of several weak interactions. (c) 2012 Elsevier Ltd.
