摘要：

Three binuclear Ag-I complexes based on beta-diketonate and N-donor ligands, [Ag-2(2,3-bpp)(2)(btfa)(2)] (1) and [Ag-2(2,3-bpp)(2)(cbtfa)(2)] (2), and [Ag-2(2,3-bpp)(2)(mbtfa)(2)] (3), where 2,3-bpp is 2,3-bis(2-pyridyl)pyrazine, Hbtfa is benzoyltrifluoroacetone, Hcbtfa is 4-chlorobenzoyltrifluoroacetone, and Hmbtfa is 4-methoxybenzoyltrifluoroacetone, were prepared and characterized by elemental analysis, IR, and H-1 NMR spectroscopy and X-ray crystallography. Thermal and electrochemical properties were also studied. The complexes are structurally quite similar. Three nitrogen atoms of 2,3-bpp in 1, 2, and 3 are donors toward two silver(I) ions in syn-conformation. Abundant weak interactions, such as pi center dot center dot center dot pi, C-H center dot center dot center dot F, and C-H center dot center dot center dot O interactions, provide additional assembly forces, leading to 3-D supramolecular networks for 1-3.
