Front Cover: Synthesis of Triple‐Stranded Diruthenium(II) Compounds (Eur. J. Inorg. Chem. 25/2022)

Abstract

The Front Cover shows the design of triple‐stranded di‐ruthenium(II) complexes from a series of ligands containing a 1,4‐disubstituted 1,2,3‐triazole. Chirality is a common motif in nature, illustrated by a tree in a rainforest, where helical and non‐helical features can arise in the same structure. This is similar to the synthesis of Ru(II) products, where mixtures of helicates and mesocates were observed from the same metal and ligand source. Ligand design played a key role in determining the product distribution, and helicate enantiomers and helicate/mesocate diastereomers were separated for some dinuclear complexes. Interestingly, the mesocate and helicate containing an n‐propyl spacer were found to exhibit extensive photo‐interconversion, a unique observation for Ru(II) compounds of this type.
