title: Bis(2-acetylpyridine-κN,O)silver(I) tetra-fluoridoborate: a complex with silver in a seesaw coordination geometry.
abstract: The reaction of 2-acetylpyridine with silver(I) tetra-fluorido-borate leads to the discrete title complex, [Ag(C(7)H(7)NO)(2)]BF(4), in the cation of which the Ag atom is coordinated by two 2-acetylpyridine ligands, each of which is N,O-bidentate, albeit with stronger bonding to the N atoms [Ag-N = 2.2018 (15) and 2.2088 (14) Å; Ag-O = 2.5380 (13) and 2.5454 (13) Å]. The four-coordinate Ag atom has a seesaw coordination geometry with a τ(4) index of 0.51. The tetra-fluoridoborate anion is disordered over two orientations with 0.568 (10):0.432 (10) occupancies.
