Three binuclear AgI complexes based on a b-diketonate and N-donor ligands, [Ag2(2,3-bpp)2(hfa)2] (1), [Ag2(2,3-bpp)2(ftfa)2] (2) and [Ag2(2,3-bpp)2(ttfa)2] (3), where 2,3-bpp is 2,3-bis(2-pyridyl)pyrazine, Hhfa is hexafluoroacetylacetone, Hftfa is furoyltrifluoroacetone and Httfa is thienoyltrifluoroacetone, were prepared and characterized by elemental analysis, IR and 1H NMR spectroscopy as well as by X-ray crystallography. Additionally, thermal and electrochemical properties were studied. The complexes are structurally similar to each other. Three nitrogen atoms of the ligand 2,3-bpp in compounds 1, 2 and 3 act as donors toward two Ag+ ions in syn-conformation. Abundant weak interactions, such as p  p, CAH  F, CAH  p and CAH  O interactions lead to 3D supramolecular networks for 1–3. .
