Swap One Cation, Warp the Whole Framework — and Two Techniques Watch It Happen
Swapping Cs for Rb for K systematically distorts the WO6 framework of a NIR-shielding tungsten bronze — mapped by single-crystal X-ray and RAMaker Raman.
9 Ligands Reveal How Tricopper(I) Clusters Bond
Swapping one ortho-substituent shifted Cu···Cu distances from 2.75 Å (bonded) to 3.59 Å (no interaction) across a nine-ligand tricopper(I) series — proof that sterics, not electronics, control these cuprophilic interactions.
