Thiamine tetraphenylborate monohydrate: a two-dimensional hydrogen-bonded network with (4,4)-topology

Abstract

The title compound, 3-[(4-amino-2-methylpyrimidin-5-yl)methyl]-5-(2-hydroxyethyl)-4-methylthiazolium tetraphenylborate monohydrate, C12H17N4OS+.C24H20B-.H2O, is a salt in which the thiamine cations are linked by hydrogen bonds into a two-dimensional network having (4,4)-topology. The stacked sheets form channels, which are occupied by the anions; the cations and anions are linked by C-H...pi(arene) hydrogen bonds.
