title: Bis[5-(pyridin-2-yl)pyrazine-2-carbo-nitrile-κN,N]silver hexa-fluorido-phosphate.
abstract: In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]PF(6), two κ(2)N,N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming a distorted N(4) tetra-hedral coordination geometry. The mononuclear units are inter-connected through π-π inter-actions [centroid-centroid distances = 3.801 (2) and 3.979 (3) Å] and the hexa-fluoridophosphate anions are embedded within the inter-stices. C N⋯π inter-actions [N⋯centroid = 3.519 (2) Å] and C-H.⋯N hydrogen-bonding inter-actions also occur.
