Description: Metal folates MFol • nH2O (M2+ = Mn2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+; n = 4–6), silver folate Ag2Fol • 3H2O, and the folic acid–imidazole conjugate H2Fol • 3Im • 2H2O were synthesized in aqueous solutions at a 1 : 1 M2+ : H2Fol molar ratio and pH 5.5–6.6. The compositions of the resulting compounds were determined by chemical, thermal, and gravimetric analysis. The composition of copper(II) folate was confirmed by elemental analysis; the solubility product of nickel folate (9.65 × 10–9) was estimated using solubility data. IR and electron absorption spectroscopy was used to show that oxygen atoms of carboxyl groups in folic acid and the pyridine nitrogen atom in imidazole are involved in bond formation in folates and the conjugate.
