Two new Krebs-type tungstoantimonates (Hen)H{[Sb(WO)(B-β-SbWO)][(WO)(WO)(B-β-SbWO)]}·22HO () and (Hen)[(WO)(WO)(B-β-SbWO)]·12HO () were synthesized and characterized. Notably, crystal possesses a specific pseudo-seesaw SbO subunit in the central metal belt of [Sb(WO)(B-β-SbWO)] species, which is rare in reported Krebs-type polyoxometalates. One of the structural features is that there are two kinds of Krebs-type polyanionic clusters in crystal labeled as {(WO)(WO)(B-β-SbWO)} (part ) and {Sb(WO)(B-β-SbWO)} (part ), respectively. The subunits and are alternately connected through Sb-O-W bonds into a chain-like structure of inorganic clusters. Moreover, the catalytic property of crystals and for electron-transfer reaction were investigated by transferring K[Fe(CN)] into K[Fe(CN)].
合成并表征了两种新型的克雷布斯型钨锑酸盐（Hen）H{[Sb(WO)(B-β-SbWO)][(WO)(WO)(B-β-SbWO)]}·22H₂O（）和（Hen）[(WO)(WO)(B-β-SbWO)]·12H₂O（）。值得注意的是，晶体在[Sb(WO)(B-β-SbWO)]物种的中心金属带中具有特定的假跷跷板SbO亚基，这在已报道的克雷布斯型多金属氧酸盐中很少见。结构特征之一是晶体中有两种克雷布斯型聚阴离子簇，分别标记为{(WO)(WO)(B-β-SbWO)}（部分）和{Sb(WO)(B-β-SbWO)}（部分）。亚基和通过Sb-O-W键交替连接成无机簇的链状结构。此外，通过将K[Fe(CN)]转化为K[Fe(CN)]研究了晶体和对电子转移反应的催化性能。
