Abstract

Abstract: A method----coordinating equilibrium competition----for synthesizing β-GaW₉ heteropolyanion is reported here.The anion was separated in the form of salts with a general formula MaHb[β-GaW₉O₃₄H]·xH₂O(M⁺=Na,K,NH₄,Me₄N,Et₄N,a+b=10).The anion is the first β-isomer of Ga-containing heteropoly complexes and it can react with Mn²⁺ ion to form anion β-GaW₉Mn₃(H₂O)₃O₃₇^11-.All the complexes prepared here are characterized by IR,UV spectra,CV,ESR,μ_eff and DTA determinations.The results show that the title complex is reactive towards the coordination reaction and has a trivacance Keggin structure.

Key words: Salt of nonatungstogallate, β-isomer, Salt of nonatungsto-trimanganogallate, Synthesis
