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 F conformation) is associated with BF4− anions via two characteristic bridging interactions between the thiazolium and pyrimidinium rings, i.e. C—H...BF4−...pyrimidinium and N—H...BF4−...thiazolium interactions. Thiamine molecules are linked by N—H...O hydrogen bonds to form a helical chain structure.
