Abstract

The reactions of one equivalent of silver(I) tetrafluoroborate with one equivalent of 4‐R‐3,6‐di(2‐pyridyl)pyridazine ligands (R = n‐C~10~H~21~, 4‐O~2~NC~6~H~4~, 4‐MeOC~6~H~4~, 4‐F~3~CC~6~H~4~, 4‐NCC~6~H~4~, 3,5‐Br~2~C~6~H~3~, 3,5‐(MeO)~2~C~6~H~3~) in acetonitrile are reported. All complexes have been structurally characterized, and are found to belong to one of four differentsolid‐state structure types: [AgL~2~][BF~4~], [Ag~2~L~2~][BF~4~]~2~, {[Ag~3~L~2~][BF~4~]~3~}~n~ and {[Ag~2~(NCMe)~2~L~2~][BF~4~]~2~}~n~. For the bulk samples of these compounds, elemental analyses are consistent with formulations of [AgL~2~][BF~4~], [Ag~2~L~2~][BF~4~]~2~, but the two polymeric complexes analyse as 1:1 Ag:L complexes. In solution, ^1^H and ^13^C NMR spectra reveal only one ligand environment at room temperature for each product.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
