eng	Aurophilic interaction in d8 complexes or enforced short contact? Investigation of diiminoisoindole coinage metal complexes	Isoindole and its derivatives already found application in multiple fields of chemistry. Among others, its use as pharmaceuticals or resistant pigments can be mentioned. A group of unsymmetrically substituted diiminoisoindoles was prepared and the coordination abilities of these ligands were systematically investigated. A significant group of prepared compounds are coinage metal complexes. These dimeric complexes contain unusually short metallophilic interactions between metal atoms in solid structure, as confirmed by X-ray crystallography. Their structure, properties and possible uses were investigated. Counterintuitively, unusually short metal-metal distances have also been reported in the case of gold(III) complexes. We can therefore assume that, even in these complexes a weak aurophilic interaction can occur within the metallacycle. This phenomenon has already been described and discussed several times in the literature, but not fully proven or understood. That is why our work aims to further explore and explain this interaction based on experimental and computational research.
