Abstract: The title compound, C6H7O2S3+·BF4-, consists of a planar 2-thioxo-1,3-dithiol-4,5-yl unit [maximum deviation from the ring plane = 0.020 (3) Å], with an ethylenedioxy group fused at the 4,5-positions; the ethylenedioxy C atoms are disordered over two positions with site-occupancy factors of 0.5. The 1,4-dioxine ring has a twist-chair conformation. Weak cation-anion SF interactions [3.022 (4)-3.095 (4) Å] and an SO [3.247 (4) Å] interaction are present.
