Manganese(II) forms different ligand complexes with 2-hydroxy-5-bromthiophenol and aminophenols with a component ratio of 1:2:2 and 1:2:1. It is established that manganese(II)  forms a complex at рН 1.6–7.8.  The complexes are extracted  with  chloroform  by  96.1–98.9%.  Optical  characteristics  (l_max=375–410 nm)  of  the complexes have been studied and their molar coefficients [ε=(1.15–2.36)∙10⁴] of absorption have been defined.
