Aurintricarboxylic acid (ATA) has been synthesized , and prepared complex with Mn(II) was characterized by spectrophotometeric methods UV-Visible, FT-IR and molar conductivity measurement. The octahedral geometry around Mn(II) ion can be suggested. The ligand used as a reagent for the spectrophotometer determination of micrograms of manganese ions. The reaction between Mn2+ and ATA form a pink complex having a molar ratio of 2:1 (M: L) at pH 7 and the stability constant was found to be (1.62x1010 L2.mole2-). The molar absorptivity of the complex is 2.55x 104L.mole-1.cm-1 at max 552 nm. This method sensitive and the complex formed high stable which can used a reagent ATA to spectrophotometric determination of the manganese (II).
