中文摘要	an investigation into the interactions between thiamine monophosphate (tmp) and anions has resulted in the preparation and x-ray characterization of the compounds (tmp)(hg2br5).0.5h(2)o (1) and (tmp)(2)(hg3i8) (2). in each compound the tmp molecule exists as a monovalent cation in the usual f conformation. the halogenomercurate anions occur in two-dimensional (2-d) network in 1 or one-dimensional (1-d) chain in 2. in both 1 and 2, the structures consist of alternating cationic sheets of the hydrogen-bonded tmp molecules and anionic sheets of the polymeric halogenomercurate anions. the tmp molecule binds to the polymeric anions through the characteristic 'anion bridge i', c(2)-h..x...pyrimidinium (x = br in 1 and 1 in 2), and electrostatic interactions between electropositive s(1) and halogen atoms. the 'anion bridge ii' of the type n(4'1)-h...x...thiazolium (x = phosphate group) plays a role in stabilizing the molecular conformation. the biological implication of the host-guest-like complexation between tmp and polymeric anions is discussed.
