11-系列不饱和杂多阴离子可作为配体与过渡金属或希土离子生成混合型杂多阴离子。由于这种无机高分子配合物对某些有机合成反应具有催化活性及抗病毒性能,新型化合物的合成仍吸引着人们的关注。11-钨钛杂多阴离子除与希土离子生成K_(13)[Ln(TiW_(11)O_(39))_2]·xH_2O型化合物外,也可与过渡金属离子生成混合型杂多阴离子。本文报道了K_n[TiW_(11)M(H_2O)O_(39)]·xH_2O(M=Mn~(2+)、Cu~(2+)、Zn~(2+)、Fe~(3+),Co~(3+)和Cr~(3+))型杂多酸盐的合成与性质。
11-series of unsaturated heteropolyanions can be used as a ligand and transition metal or rare earth ions to generate mixed heteropolyanions. Due to the catalytic activity and antiviral activity of such inorganic polymer complexes for some organic synthesis reactions, the synthesis of novel compounds still attracts the attention. 11-Tungsten-Titanium Heteropoly Anions In addition to K_ (13) [Ln (TiW_ (11) O_ (39)) _2] · xH_2O-type compounds with rare earth ions, mixed heteropolyanions can also be formed with transition metal ions. In this paper, K_n [TiW 11 M (H 2 O) O 39] xH 2 O (M = Mn 2+, Cu 2+, Zn 2+, Fe 3+) , Co ~ (3+) and Cr ~ (3+)) heteropolyacid salts.
