The infrared and Raman spectra of the ligands; 2-(alpha-hydroxybenzyl)thiaminium chloride (HBT), 2-(alpha-hydroxycyclohexylmethyl)thiaminium chloride (HCMT), and their protonated forms. HBT.HCl and HCMT.HCl, as well as of their zwitterionic type complexes Zn(HBT)Cl3, Cd(HBT)Cl3, Hg(HBT)Cl3 and Zn(HCMT)Cl3, Cd(HCMT)Cl3, Hg(HCMT)Cl3, have been recorded in the region 4000-50 cm-1. Several characteristic band have been identified or tentatively assigned and are discussed in relation to the structures of the complexes. It is concluded from the spectra that the complexes are isostructural and that the bonding site of the ligands is the N(1') atom of the pyrimidine moiety. (EN)
