查询词典 alternating function

In their structures, polyanions are bridged by Ln ions via the coordination of the bridging oxygen atoms and terminal oxygen atoms, forming a W–Ot′–Ln–Ob–W linkage; and through the W–Ot′–Ln–Ob–W linkage a one-dimension infinite linear chain with alternating cations and anions is formed.

在相似的合成条件下，我们向原有体系内加入顺丁烯二酸作为有机配体，合成了化合物7，其7的基本结构和化合物1-6很相似，但有一个顺丁烯二酸阴离子取代了一个NO3-离子的位置。

Inthe compound, Pr~(3+) cations are eight-coordinated with oxygen atomsfrom six DMSO molecules, two polyanions. The crystal structureindicates that the compound forms a one-dimensional zigzag chain builtfrom the alternating polyanions and cationic units throughW-O_d-Pr-O_d-W links.

结构分析结果表明，化合物中Pr~(3+)离子为八配位，配位氧原子分别来自6个NMP分子和二个杂多阴离子的端氧原子，金属配阳离子与杂多阴离子骨架通过W-O_d-Pr-O_d-W相连。
