文摘

The o-palladated, chloro-bridged dimers [Pd{2-phenylpyridine(-H)}-渭-Cl]₂ and [Pd{N,N-dimethylbenzylamine(-H)}-渭-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鈭? 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)}-渭-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鈭? ligands: cage-closure in this latter system appears to be inhibited by steric crowding of the thiocarbonyl groups.
