Are i‐Motif Structures in DNA Compatible with Cytosine–Ag(I)–Cytosine Base Pairs?

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
An i‐motif/duplex junction was evaluated with respect to its ability to replace the protons from the hemi‐protonated C:CH+ pairs by AgI ions to form C–AgI–C base pairs. Interestingly, only one such metal‐mediated base pair can be formed before the oligonucleotide rearranges into a duplex structure.

Heterobimetallic Pt(II) Complexes Supported by 1,8‐Naphthyridine Ligands Confirm the Rotation of C6F5 Groups about the Pt−C Bond

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
You Spin Me Round. The ligand 1,8‐naphthyridine is able to stabilize heterobimetallic complexes containing Pt(II)→M (M = Ag, Cu) donor–acceptor bonds, in which the rotation of the C6F5 ligands in solution can be stopped at low temperature. The ligand 1,8‐naphthyridine (napy) exhibits a rich coordination chemistry arising from the disposition of its two
