Crystalline Li(I), Na(I), K(I), Mg(II), Ca(II), Sr(II), Ba(II) and Cd(II) salts of inosine 5′‐monophosphoric acid, H 2 (IMP), were obtained and characterized by Raman spectroscopy. Splitting of the imidazolic 1480 cm −1 band was observed for the N(7)‐bound Ca(IMP)·6H 2 O, Ba(IMP)·6H 2 O, Sr(IMP)·6H 2 O and Cd(IMP)·4H 2 O compounds. The Li(I), Mg(II), Ca(II) and Cd(II) ions bind directly to the phosphate group, and no direct coordination involving the carbonyl C(6)O group was observed in the compounds reported here. Some Raman spectral features in the 750–700 cm −1 range seem to reflect the nucleoside structure of the inosine moiety
