A macrocyclic hexanuclear palladium complex, which accumulates coordination sites on metals inside the cavity, was synthesized. The macrocycle was found to take a uniquely-twisted C2-symmetric conformation when six molecules of a bulky pyridine derivative coordinated to the palladium.

We report herein the synthesis and full spectroscopic characterization of two AB-corrole phosphonic acids. Thanks to the presence of a phosphonic acid functional group at the 10--position, the corroles were covalently linked to the hexanuclear Zr clusters of a PCN-222 metal-organic framework (MOF). After the insertion of cobalt into the corrole macrocycle, the metal complexes are able to bind small volatile molecules such as carbon monoxide (CO).

Metallomacrocycles with internal coordination sites have a high potential to precisely control the positions of the guest ligands and the overall shape of the assemblies by utilizing the directionality and reversibility of the coordination bonds. However, when such coordinative hosts possess multiple coordination sites, it was difficult to control to which coordination sites the incoming guest ligands bind, because such systems often result in a random, uncontrolled mixture. The metallomacrocycle that we now report, a hexanuclear palladium complex of hexapap possessing six internal coordination sites, can take two different conformations depending on the guests.

Four hexanuclear chloride and sulphate Ni(II) and Cu(II) complexes 1, 2, 4 and 5 and one tetranuclear nitrate Cu(II) complex 3 have been synthesised from appropriate metal salts and 6 + 6 octadecaaza macrocyclic ligands. All obtained coordination compounds have been characterised by elemental analysis, spectroscopic methods (ESI MS, NMR and EPR), magnetic susceptibility measurements and X-ray crystallography. Their X-ray crystal structures reveal different coordination modes of metal cations involved in the obtained centro-symmetrical coordination compounds.

Dialumane 1 reacts with pyridines at elevated temperatures through regioselective reductive dehydrogenation of 4-H, affording a unique hexanuclear Al(iii) macrocycle [{LAl(pyridyl)}6], which represents the first dialumane-mediated C-H activation of Py and may suggest a new approach toward organometallo supra-molecules by one-pot small molecule activation and self-assembly.

The design of structurally defined heteroleptic coordination cages is a challenging task, and only few examples are known to date. Here we describe a selection approach that allowed the identification of a novel hexanuclear Pd cage containing two types of dipyridyl ligands. A virtual combinatorial library of [PdL](BF) complexes was prepared by mixing six different dipyridyl ligands with substoichiometric amounts of [Pd(CHCN)](BF).
