In the title mononuclear complex, [Ag(C9H7N3S)2]BF4, the AgI ion adopts a virtually linear coordination geometry [N-Ag-N = 178.06 (11)°] with the two ligands bound to the metal atom via the pyridine N atoms. The metal-coordinated pyridine rings are almost coplanar, making a dihedral angle of 1.5 (2)°, while the two pendent pyrazine rings are arranged on the same side of the N-Ag-N line. Along the a axis, the mononuclear coordination units are stacked with [pi]-[pi] interactions between the pyridine rings [centroid-centroid distance = 3.569 (4) Å], leading to infinite chains. The chains are interconnected through intermolecular N(pyrazine)...[pi](pyrazine) interactions forming layers parallel to the ab plane [N...centroid = 3.268 (5) Å]. These layers are further stacked along the c-axis direction, furnishing a three-dimensional supramolecular framework with the tetrafluoridoborate anions embedded within the interstices.
