This paper describes a proposed mechanism of the formation of crystalline thiamine-copper complex (I) and also presents a brief discussion on a relationship to other related compounds. The overall reaction leading from thiamine to I is shown as follows. [chemical formula] Paper chromatographical studies have revealed that ethylene glycol which has the distinctive property of dissolving I, can dissociate I into its components, but not with other less efficient solvents such as ethanol, butanol, or glycerine. From a consideration of the results of dialysis or paper chromatographical studies, or UV spectra, the mode of combination of the units will be discussed in connection with the 4-coordinative character of copper atom.
