%X In the title mononuclear complex, [Ag(C9H7N3S)2]BF4, the AgI ion adopts a virtually linear coordination geometry [N¡ªAg¡ªN = 178.06 (11)¡ã] 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)¡ã, while the two pendent pyrazine rings are arranged on the same side of the N¡ªAg¡ªN line. Along the a axis, the mononuclear coordination units are stacked with ¦Ð¨C¦Ð interactions between the pyridine rings [centroid¨Ccentroid distance = 3.569 (4)  ], leading to infinite chains. The chains are interconnected through intermolecular N(pyrazine)...¦Ð(pyrazine) interactions forming layers parallel to the ab plane [N...centroid = 3.268 (5)  ]. These layers are further stacked along the c-axis direction, furnishing a three-dimensional supramolecular framework with the tetrafluoridoborate anions embedded within the interstices.
