Abstract

In the title salt, {[Ho(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n), the anion forms a W/S/Ag polymeric chain along the a axis. The holmium atom in the cation is coordinated by eight O atoms from two nitrate and four hexa-methyl-phospho-ramide ligands in a distorted square-anti-prismatic geometry. Together with the two nitrate ligands, the complex cation in the title compound is univalent, which leads the anion to be univalent as well. The polymeric anionic chain with W-Ag-W and Ag-W-Ag angles of 161.429 (17) and 153.608 (10) °, respectively, presents a distorted linear configuration. The title complex is isotypic with the corresponding Y, Yb, Eu, Nd, La and Dy analogues.

摘要

在标题盐{[Ho(NO₃)₂(C₆H₁₈N₃OP)₄][AgWS₄]}ₙ中,阴离子沿a轴形成W/S/Ag聚合物链。阳离子中的钬原子由来自两个硝酸根和四个六甲基磷酰胺配体的八个O原子以扭曲的四方反棱柱几何构型配位。与两个硝酸根配体一起,标题化合物中的复合阳离子为单价,这也使得阴离子为单价。具有W-Ag-W和Ag-W-Ag角分别为161.429 (17)°和153.608 (10)°的聚合物阴离子链呈现出扭曲的线性构型。标题配合物与相应的Y、Yb、Eu、Nd、La和Dy类似物同型。
