Bis[5-(2-pyrid­yl)pyrazine-2-carbonitrile]­silver(I) tetra­fluorido­borate

In the title mononuclear complex, [Ag(C(10)H(6)N(4))(2)]BF(4), the Ag(I) atom adopts a square-planar N(4 )coordination geometry and is surrounded by two 5-(2-pyrid­yl)pyrazine-2-carbonitrile ligands. The tetra­fluorido­borate anions link the mononuclear cations through inter­molecular C—H⋯F hydrogen-bonding inter­actions, forming an infinite tape structure along [110]. Other weak inter­actions occur: π–π stacking with centroid–centroid distances of 3.820 (2) and 3.898 (1) Å between pyridyl rings and 3.610 (2) and 3.926 (2) Å between pyrazinyl rings as well as F⋯π contacts involving the tetra­fluorido­borate anions and pyrazine rings [F⋯centroid = 2.999 (3) Å]; these combine with the hydrogen-bonding inter­actions to link the mononuclear cations into a three-dimensional supra­molecular architecture.
