The title radical anion salt was prepared and its structure determined by XRD. Crystal packing of the salt displays a layered structure featuring belts of the radical anions connected by S···N contacts. Magnetic measurements on the salt in the temperature range of 2–300 K reveal antiferromagnetic interactions (J = –4.2 0.7 cm–1). Theoretical calculations suggest that the salt possesses a 2D magnetic structure. Color code: gray = C, violet = Co, light gray = H, blue = N, yellow = S.
