Tuning the Size and Geometry of Heteroleptic Coordination Cages by Varying the Ligand Bent Angle

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Rujin Li

Spherical assemblies of the type [PdnL2n]2n+ can be obtained from PdII salts and curved N-donor ligands, L. It is well established that the bent angle, α, of the ligand is a decisive factor in the self-assembly process, with larger angles leading to comple ...

Bronsted and Lewis acid adducts of triazenes

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Abdusalom Suleymanov, Frederick Mark Chadwick, Iris Roswitha Landman

The synthetic utility of triazenes rests on the fact that the triazene function can be cleaved by BrOnsted or Lewis acids, liberating diazonium compounds. However, the preferred coordination site of the acid is still a matter of debate. We have analyzed tr ...
