In the title compound, [Ag(C12H8N2S)2]BF4, the two-coordinate AgI ion lies on a crystallographic inversion center and is linearly bonded to the N-donor atoms of two separate quinoxaline ligands. The thiophenyl ring of the ligand is nearly coplanar with the quinoxaline ring system [dihedral angle = 9.15 (13)°]. In the crystal, the complex molecules pack in layers parallel to (-102) and form weak [pi]-[pi] ring stacking interactions [minimum ring centroid separation = 3.7054 (17) Å]. The tetrafluoridoroborate anion is equally disordered about an inversion center.
