Bis[5-(pyridin-2-yl)pyrazine-2-carbo­nitrile-κ2 N 4,N 5]silver hexa­fluorido­phosphate

Abstract

In the mononuclear title complex, [Ag(C10H6N4)2]PF6, two κ2 N,N′-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the AgI atom, forming a distorted N4 tetra­hedral coordination geometry. The mononuclear units are inter­connected through π–π inter­actions [centroid–centroid distances = 3.801 (2) and 3.979 (3) Å] and the hexa­fluoridophosphate anions are embedded within the inter­stices. C N⋯π inter­actions [N⋯centroid = 3.519 (2) Å] and C—H.⋯N hydrogen-bonding inter­actions also occur
