The iron(III) thiobarbiturate (Fe(HthioBar)3∙nH2O) synthesis was carried out at 5 °C and pH ≈ 2,5. The product is represented by a crystalline slightly soluble in water powder of brown color. The water molecules number (n) was determined in the sample via gravimetry and thermogravimetry (n = 5). Besides, dominant complex particle composition at pH ≈ 2,3 in the Fe3+ – H2thioBar system ([FethioBar]+) and its stability constant (β1 = 1,0∙1011) were defined via spectrophotometry and pH-metry.
