Interactions of thiamine with polymeric halogenocadmate anions in the organic-inorganic hybrid compound (thiaminium)[Cd3Br4.4Cl3.6].
The structure of poly[3-[(4-amino-2-methylpyrimidin-1-ium-5-yl)methyl]-5-(2-hydroxyethyl)-4-methylthiazolium octa-mu-bromo/chloro(4.4/3.6)-tricadmate(II)], [(C12H18N4OS)[Cd3 Br4.41Cl3.59]]n consists of hydrogen-bonded thiamine molecules and polymeric cadmium bromide/chloride anions in an organic-inorganic hybrid fashion. The one-dimensional anion ribbons are formed by edge-sharing octahedra and vertex-sharing tetrahedra. Thiamine molecules adopting the S conformation are linked to anions via three types of interactions, namely an N(amino)-H...anion...thiazolium bridging interaction, an N(pyrimidine)-H...anion hydrogen bond and an O(hydroxy)-H...anion hydrogen bond.
