Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials

Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.
A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

Chemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

A Low‐Symmetry FeII Tetrahedron From a Flexible Tritopic Ligand

Chemistry – A European Journal, EarlyView.
A highly symmetric and flexible tris‐bidentate tritopic ligand forms an S4 meso homoleptic face‐capped FeII tetrahedron near‐quantitatively in acetonitrile. The addition of nitromethane solvent causes partial isomerization of this meso cage to the racemic homochiral tetrahedron, with the complexity of the system being moderated through solvophobic ...
