The elemental analysis, magnetic susceptibility and thermogravimetryhave been determined for the solid complex of HEH(EH)P-Mn(Ⅱ) and the infraredspectrum has been carried out in comparison to the extractant HEH(EH)P. The extra-cted compound has also been studied by electronic and electron spin resonance spec-troscopy in octane solvent and solid state at room temperature. On the basis of themeasurements, it is concluded that the structure of the solid polymeric species MnA_2is in a tetrahedral arrangement.
