Pairwise assembly of organopalladium(II) units with cyanurato(3-) and trithiocyanurato(3-) ligands: formation of chiral Pd12, Pd10, and Pd9 cage-molecules

posted on 2023-06-09, 12:49 authored by Claire A Murray, Christine J Cardin, Barnaby GreenlandBarnaby Greenland, Andrew Swift, Howard M ColquhounThe o-palladated, chloro-bridged dimers [Pd{2 phenylpyridine(-H)}-µ-Cl]2 and [Pd{N,N-dimethylbenzylamine(-H)}-µ-Cl]2 react with cyanuric acid in the presence of base to afford closed, chiral cage-molecules in which 12 organo-Pd(II) centers, located in pairs at the vertices of an octahedron, are linked by four tetrahedrally arranged cyanurato(3-) ligands. Incomplete (Pd10) cages, having structures derived from the corresponding Pd12 cages by replacing one pair of organopalladium centers with two protons, have also been isolated. Reaction of [Pd{2-phenylpyridine(-H)}-µ-Cl]2 with trithiocyanuric acid gives an entirely different and more open type of cage-complex, comprising only nine organopalladium centers and three thiocyanurato(3-) ligands: cage-closure in this latter system appears to be inhibited by steric crowding of the thiocarbonyl groups.
