Abstract: K6Z(H2O)MnW11O39·xH2O(Z = Zn, Ni)and K13Ln(MnW11O39)2·xH2O (Ln = La,Nd)were prepared and characterized by spectral and thermogravimetric analyses.The charge ofheteropolyanions in aqueous solution and their alkalinity was 13 as determined by conduc-tometric titration.The complexes are stable in aqueous solution of pH 3.8 to 6.3.

Key words: heteropoly complex, potassium 11-tungstomanganate, lanthanide, transition elemenf
