摘要: 利用还原-氧化重构法(简称ROR法)合成了具有Strandberg型含硒的杂多化合物K3Na·[Se2Mo5O21]·2H2O的单晶,结构测定表明,此化合物属单斜晶系,阴离子包含通过共边和共顶点相连的五聚MoO6八面体,组成八面体的5个金属原子近似形成五角平面骨架,2个SeO3三角锥加在五角平面的上下方。

关键词: 硒, 钼, 杂多阴离子, 晶体结构

Abstract: By red-ox reconstructing (ROR) method, we synthesized and analyzed the het eropoly compound K3Na[Se2Mo5O21]·2H2O with Strandberg-type structure.The crystals are the polyanion, five MoO6octahedra are connected by edge sharing, and the two octahedra at the two ends are connected by conner sharing to complete the Mo5ring, the two SeNO3trigonal pyramids are attached to the ring from above and below the ring.

Key words: Se,Mo, Heteropolyanion, Crystal structure
