The [enPd(II)]2+ (en = ethylenediamine) unit has emerged as a versatile building block in molecular self-assembly. In particular, the 90° coordination angle of the metal has been judiciously used in the design of new discrete two- and three-dimensional structures. Our last 15 years of work with the Pd(II)-cornered unit is summarized in this Account, from the spontaneous formation of a Pd4 square metal complex to a family of architectures such as cages, bowls, boxes, tubes, catenanes, and spheres

This article reviews recent progress in the study of the transition-metal mediated self-assembly of two- and three-dimensional synthetic receptors. Whereas macrocyclization under kinetic control is undoubtedly an unfavorable process, the self-assembly strategy offers quite efficient methods for constructing macrocycles under thermodynamic control. In particular, cis-protected Pd(II) and Pt(II) blocks are quite effective in obtaining the cyclic framework from simple molecules. Examples disclosed

This article deals with a coordination approach to three-dimensional assemblies via ‘molecular paneling’. Families of planar exo-multidentate organic ligands (molecular panels) are found to assemble into large three-dimensional assemblies through metal-coordination. In particular, cis-protected square planar metals, (en)Pd2+ or (en)Pt2+ (en = ethylenediamine), are shown to be very useful to panel the molecules. Metal-assembled cages, bowls, tubes, capsules, and polyhedra are efficiently construc

Drawing inspiration from the self-assembly of hollow spherical virus capsids and protein cages found in nature, a family of roughly spherical coordination polyhedra with general formula MnL2n was designed and several members of the series have been synthesised. These spherical complexes are self-assembled upon reaction of bent bis(pyridine) ligands with Pd(2+) ions. The introduction of functional side chains into the ligands is straightforward, making the synthesis of both exo- and endohedrally

Intrigued by transannular interactions occurring in stacked aromatic molecules, chemists have long endeavored to engineer discrete stacks of specific lengths and orientation. The maturation of self-assembly methodologies has shifted the focus away from utilizing covalent scaffolds to harnessing non-covalent interactions such as ionic interactions, hydrogen bonds, metal-ligand interactions, and aromatic interactions. Aromatic molecules often assemble into ill-defined, infinite aggregates and thus

The structure of a molecular square assembling from [Pd(en)(NO3)2] 3 and 4,4′-bipyridine is confirmed by X-ray crystallography, whereas squares assembling from 3 and larger ligands, py-X = py (py = 4-pyridyl, X = CHCH, CC, P-C6H4) are shown to exist in equilibrium with molecular triangles.
