Abstract

In the title compound, 3‐[(4‐amino‐2‐methyl‐5‐pyrimidin‐1‐io)methyl]‐5‐(2‐hydroxy­ethyl)‐4‐methyl­thia­zolium(2+) bis(tetra­fluoro­borate), C12H18N4OS2+·2BF4−, the divalent thia­mine cation (in the Fconformation) is associated with BF4−anions viatwo characteristic bridging interactions between the thia­zolium and pyrimidinium rings, i.e.C—H⃛BF4−⃛pyrimidinium and N—H⃛BF4−⃛thia­zolium interactions. Thi­amine mol­ecules are linked by N—H⃛O hydrogen bonds to form a helical chain structure.
