  Molecular Catenation via Metal-Directed Self-Assembly and π-Donor/π-Acceptor Interactions:  Efficient One-Pot Synthesis, Characterization, and Crystal Structures of [3]Catenanes Based on Pd or Pt Dinuclear Metallocycles

  摘要：

  Dinuclear square metallocycles 3a,b assemble spontaneously when M(en)(OTf)(2) (M = Pd, Pt) and a 4,4'-bipyridinium ligand are mixed in acetonitrile. Six new [3]catenanes were prepared in good yields by thermodynamically driven self-assembly reaction of molecular squares 3a,b and pi-complementary dioxoaryl cyclophanes. Single-crystal X-ray analyses of the [3]catenanes revealed the insertion of two aromatic units inside the metallocycle cavity. The structures are stabilized by means of a combination of pi-pi stacking, [C-H center dot center dot center dot pi] interactions, and [C-H center dot center dot center dot O] hydrogen bonds. [3]Catenane (DB24C8)(2)-(3a) showed in solid-state two external DB24C8 rings positioned over the Pd(en) corners, which are held in position by [N-H center dot center dot center dot O] hydrogen bonds. Furthermore, formation of catenane (DB24C8)(2)-(3a) can be switched off and on in a controllable manner by successive addition of KPF6 and 18-crown-6.

  4′-bipyridine and palladium or platinum square-planar cis complexes. The palladium (4a,b) or platinum (5a,b) square metallocycles were obtained as 1:1 regioisomeric mixtures depending on which pair of coordinative nitrogen atoms binds to the metal center. The squares display a π-deficient cavity suitable to incorporate two π-donor aromatic systems. Therefore, the reaction with macrocyclic polyethers (BPP34C10
