Description
Sizwe Zamisa and co-authors reported in 2026 the crystal structure of a silver complex built from cage-like phosphorus ligands. One silver ion sits at the center, gripped by four of the cage ligands, three of them carrying an extra proton, and the whole assembly's charge is balanced by two carbonate ions. The crystal adopts a high-symmetry rhombohedral form.
The silver's four bonds spread in a near-perfect tetrahedron, with measured lengths reported to high precision. Silver and one phosphorus atom lie on a threefold axis, as does one carbonate carbon. Hydrogen bonds tie the protonated ligands to the carbonates, stitching the packing. The authors present the structure as a reference point for this ligand family's coordination habits. Such cages are used in catalysis and medicine design.
