Frontispiz: The Interplay Between Component Denticity and Flexibility Promotes the Formation of [AgI⋅⋅⋅AgI]-stabilised Links and Knots

Abstract

The balance between the flexibility of the bipyridine-based diamine and the coordination domain's denticity drives the self-assembly of four distinct [Ag⁺⋅⋅⋅Ag⁺]-stabilized architectures, as reported by Bartosz Szyszko et al. in their Communication (e202423962). Using 2,6-diformylpyridine leads to the formation of molecular tweezer, trefoil knot, and Solomon links, while a 1,8-naphthyridine-based dialdehyde favors [2]catenanes and trefoil knot. The Frontispiece art accentuates the unique Solomon link architecture by depicting two interlocked, snake-like motifs that guard their cherished silver eggs.
