“…The number of gold(I) complexes with gold(I)pyridyl bonds is lower than those with other ligands, such as gold(I)-phosphanes, due to the lower strength of the Au-N bond, but they deserve to be investigated. [16][17][18][19] The second coordination position of the designed complexes contains a chromophore in order to introduce luminescence properties to the resulting systems. In-depth analysis of their aggregation and luminescence has been conducted.…”

The reaction between 2,2′‐bis(3‐aminopyridyl) diselenide (L) and metal transition salts results in the formation of molecular or cluster complexes. The structural elucidation of the synthesized complexes [CuCl2(L)] (1), [Cu(3‐NH2PySeO2)2]·2H2O (2), [Cu4(3‐NH2PySe)4]·dimethylformamide (3), [CoCl2(L)] (4), [ZnCl2(L)] (5), and [Ag6(3‐NH2PySe)6] (6) demonstrates the coordination of nitrogen atoms to CuII, CoII, and ZnII, and that of the selenium atoms to CuIand AgI, which agrees with Pearson’s hard and soft acids and bases (HSAB) theory. Furthermore, the oxidation of selenium with the formation of 3‐aminopyridylseleninate [3‐NH2PySeO2]−bonded to the copper atom was observed in complex2. The antimicrobial action of complexes1,2,4, and5was evaluated againstMycobacterium fortuitum,Mycobacterium massiliense, andMycobacterium abscessus.It was observed that all these complexes have potential antimicrobial activity compared with the free ligand and metal salts used in the synthesis.
