摘要
本文以不饱含[ASW_9O_(33)]~9和[P_2W_(12)O_(48)]~12为结构单元,综述了一系列非经典结构杂多阴离子的缩聚方式及其结构特征。这些杂多阴离子的结构由简单到复杂,其分子量由小至大,目前有人已合了分子量近于11200之巨的N_(a27)[N_aA(34)W_(40)O_(140)]·45—50H_2O和[KA_(S4)W_(40)O_(140)Ag^4]^(23-)等无机高分子大环杂多化分物。
The paper overviews how to prepare a series of heteropolyanions with non--classical structures by condensation and their structural characterizations if considered unsaturated [AsW_9O_(33)]^(9-) and [P_2W_(12)O_(48)]^(12-) as the building blocks, The structures of the heteropolyanions change from simple to complex,and their molecular weights change from smal11 to large. Now many inorgnical large heteropoly complexes have been prpared, such as Na27[NaAS_4W_(40)O_(140)]·45--50H_2O and CKAS_4W_(40)OAg_4]^(23-), their molecular weights are almost 11200.
