摘　　要：在水中由Na2 WO4 ·2H2 O ,Na2 MoO4 ·2H2 O和KH2 PO4 ·2H2 O反应生成具有半Dawson结构的钨钼混配杂多阴离子Na9PW6Mo3O34 ·1 0H2 O。以阴离子和过渡金属硝酸盐为原料在水溶液中合成了一系列过渡金属二取代的具有Keggin结构的杂多酸四丁基铵盐 [TBA]4 Hn[PW7Mo3M2 O38(H2 O) 2 ]·C3H6O(n =1 ,M =Fe3+;n =3,M =Mn2 +,Co2 +,Ni2 +,Cu2 +) ,用元素分析和波谱进行了表征。The mixed anion of molybdenum tungsten,Na 9PW 6Mo 3O 34 ·10H 2O with half Dawson structure,has been synthesized from Na 2WO 4·2H 2O,Na 2MoO 4·2H 2O and KH 2PO 4·2H 2O in water.A series of transitional metal disubstituted ternay heteropolyoxometalates, [TBA] 4H n[PW 7Mo 3M 2O 38 (H 2O) 2]·C 3H 6O(n=1,M=Fe 3+ ;n=3,M=Mn 2+ ,Co 2+ ,Ni 2+ ,Cu 2+ ),have been prepared in the reaction of the anion and the corresponding salts of the transitional metal in water.They were characterized by element analysis,IR spectra and electronic spectra.
