“…16). 31 P{ 1 H} NMR spectrometry on 65 revealed two coupled doublets, supporting the heteroleptic coordination environment. A computational study on a model Pt II complex was performed in order to estimate the energy difference between homoleptic coordination and heteroleptic coordination (Fig.…”

Over the last two decades the field of metallosupramolecular self-assembly has emerged as a promising research area for the development of intricate, three-dimensional structures of increasing complexity and functionality. The advent of this area of research has strongly benefited from design principles that considered the ligand geometry and metal coordination geometry, thus opening up routes towards rationally designed classical (Archimedean or Platonic) architectures. In this tutorial review, we will focus on more recent developments in the design and synthesis of three-dimensional suprastructures which have non-classical architectures (non-Archimedean/Platonic solids) and we will explicitly address the secondary effects responsible for their formation. Three classes of metallosupramolecular assemblies will be discussed: architectures formed through the combination of a single ligand and metal, heteroleptic structures and heterometallic structures. It is hoped that our exposition may suggest how different principles employed in these three classes of structures might be combined to create even greater complexity and potential for function.

“…[59] Despite this assembly route having been known for over a decade, however, there are only a few [2]catenanes based on discrete metallocages so far. [33,[60][61][62][63] The first [2]catenane based on metallocages was prepared by Fujita and co-workers in 1999. [59] As shown in Figure 23, the [2]catenane consists of two identical metallocages [Pt 3 (en) 3 (L 30 )(tpt)] 61 , which is assembled from one molecular 21 .…”

This article describes the developments in coordination self-assembly based on flexible tripodal ligands with different metal species. Various finite metallocages such as M3 L2 , M6 L8 , M6 L4 , M4 L4 and different catenanes based on discrete metallocages constructed from flexible tripodal ligands with suitable metal species are presented here. Many M3 L2 metallocages based on ligands L(1) -L(12) and different two-coordinated metal species have been prepared, in which various Ag(I) salts and other metal species that have been protected by suitable groups, such as Zn(OAc)2 , ZnBr2 , and PdBr2 , have been used as effective acceptors. All of the M6 L8 -type metallocages are constructed from ligands L(2) or L(12) -L(20) and different four-coordinated metal species, such as various palladium(II) salts or NiCl2 , and have similar topological structures. Only a few discrete M6 L4 -type metallocages, based on ligands L(21) -L(24) , have been reported, using different strategies such as protecting groups and steric hindrance. All of the M4 L4 -type cages have similar topological structures and are constructed from ligands L(25) -L(29) with multiple donor sites. More intriguing interlocking ensembles constructed from discrete metallocages are also described here in detail, namely, three [2]catenanes based on ligands L(30) -L(32) and four polycatenanes based on ligands L(33) -L(34) .

“…More recently, Kuroda and co-workers synthesised a monomeric Pd 2 L 4 cage that could be quantitatively converted to the catenated dimer upon heating. 68 Similarly, Clever and coworkers were able to control reversible catenation of metallosupramolecular cage structures through titration of halide anions, small enough to sit within the cavity of the cage dimer and negate the positive charges of proximal palladium ions. Surprisingly, addition of an excess of halide ions resulted in displacement of ligands to give a metallo- [3]-catenane composed of three interlocked dinuclear metallocycles (Fig 15).…”

The use of metal ions to template the synthesis of catenanes by Sauvage and co-workers was a pivotal moment in the development of the field of interlocked molecules. In this Review Article we shall examine the different roles metal-ligand interactions play in modern syntheses of interlocked molecules and materials, with a particular focus on seminal contributions and the advantages and disadvantages of employing metal ligand interactions.
