“…Molecules of 9 are linked by an intermolecular Hg⋅⋅⋅CC π interaction (3.768 Å). Another interesting feature of the complex is the formation of a metallohelicate structure (Figure 2) along the Hg II ⋅⋅⋅Pd II ⋅⋅⋅Hg II axis 16. Metal‐containing helical species are the focus of attention because of their similarity with bioinorganic systems and their application in asymmetric catalysis.…”

“…Clearly, the combination of two different metal cations in a single discrete aggregate largely increases the accessibility of new structural motifs and geometries. To date, manifold structures were described, amongst others macrocycles, helicates, tetrahedra, trigonal bipyramids, cubic and prismatic cages, and unique assemblies like adamantoid cages and waterwheel‐, tweezer‐ and butterfly‐shaped complexes …”

Metallosupramolecular chemistry has attracted the interest of generations of researches due to the versatile properties and functionalities of oligonuclear coordination complexes. Quitean umber of different discrete cages were investigated, mostly consisting of only one typeo fl igand and one type of metal cation. Looking for ever more complex structures, heterobimetallic complexes became more and more attractive, as they give access to new structural motifs and functions. In the last years substantial success has been made in the design ands ynthesis of cages consisting of more than one type of metal cations, and ar apidly growingn umber of functional materials has appeared in the literature. This Minireview describes recent developments in the field of discrete heterometallic macrocyclesa nd cages focusingo nf unctional materials that have been used as host-systems or as magnetic, photo-active,r edox-active, and even catalytically active materials.

“…Introducing two different types of metal cations within one discrete aggregate offers the chance to combine the symmetry elements of both metal centers, and hence, access new geometries. Reliable design strategies like the complex-as-a-ligand approach made the assembly of heterobimetallic structures predictable; hence, there is a rapidly growing number of heterobimetallic structures that has recently been described in the literature, such as, e.g., helicates [ 27 – 28 ], cubes [ 29 – 31 ], trigonal bipyramids [ 21 , 32 – 33 ], boxes [ 34 – 36 ], prismatic cages [ 37 ], or some truly unique other shapes [ 38 – 39 ]. At the same time, heterobimetallic cages not only offer the chance to obtain new geometries, the combination of two different metal cations within one aggregate might also lead to enhanced or even entirely new properties and functions [ 40 ].…”

Employing 4-ethynylaniline as a simple organic ligand we were able to prepare the stable trans-bis(acetylide)platinum(II) complex [Pt(L1)2(PBu3)2] as a linear metalloligand. The reaction of this metalloligand with iron(II) cations and pyridine-2-carbaldehyde according to the subcomponent self-assembly approach yielded decanuclear heterobimetallic tetrahedron [Fe4Pt6(L2)12](OTf)8. Thus, combination of these two design concepts – the subcomponent self-assembly strategy and the complex-as-a-ligand approach – ensured a fast and easy synthesis of large heterobimetallic coordination cages of tetrahedral shape with a diameter of more than 3 nm as a mixture of all three possible T-, S 4- and C 3-symmetric diastereomers. The new complexes were characterized by NMR and UV–vis spectroscopy and ESI mass spectrometry. Using GFN2-xTB we generated energy-minimized models of the diastereomers of this cage that further corroborated the results from analytical findings.
