Through simple aqueous assembly strategy of Na2WO4·2H2O,NaAsO2,L-alanine(L-ala)and RE(NO3)3·6H2O in acidic aqueous solution with the attendance of dimethylamine hydrochloride [1],several kinds of organic-inorganic hybrid L-alaine-decorated and RE-substituted arsenotungstates [H2N(CH3)2]9Na4H3[RE4W8(H2O)10(L-ala)2O19(OH)2(B-α-AsW9O33)4]·nH2O(RE = HoⅢ,ErⅢ,n = 50; RE = YbⅢ,LuⅢ,n = 43)for type 1,[H2N(CH3)2]13Na2H2[RE4W7Na(H2O)10(L-ala)3O18(B-α-AsW9 O33)4]·50H2O(RE = EuⅢ)for type 2 and [H2N(CH3)2]13Na2H1[RE4W8(H2O)8(L-ala)4O19(OH)2(B-α-AsW9 O33)4]·54H2O(RE = TbⅢ,GdⅢ)for type 3 have been prepared and structurally characterized by IR spectra,elemental analysis,single-crystal X-ray diffraction and thermogravimetric analyses.
