In the title compound, {[Er(NO3)2(C6H18N3OP)4][AgWS4]} n , the polymeric anionic chain {AgWS4} n extends along [001]. The Er(III) atom in the cation is coordinated by eight O atoms from two bidentate nitrate anions and four hexa-methyl-phospho-ramide ligands in a distorted square-anti-prismatic geometry. Together with the two nitrate ligands, the cation is monovalent, which leads to the anionic chain having a [WS4Ag] repeat unit. The polymeric anionic chain has a distorted linear configuration, with W-Ag-W and Ag-W-Ag angles of 161.37 (2) and 153.548 (12)°, respectively. The title complex is isotypic with the Y, Yb, Eu, Nd, La, Dy, Sm, Lu and Tb analogues.
在标题化合物{[Er(NO₃)₂(C₆H₁₈N₃OP)₄][AgWS₄]}ₙ中，聚合阴离子链{[AgWS₄]⁻}ₙ沿[001]方向延伸。阳离子中的Er(III)原子由两个双齿硝酸根阴离子的八个O原子和四个六甲基磷酰胺配体配位，呈扭曲的四方反棱柱几何构型。阳离子与两个硝酸根配体一起呈单价，这导致阴离子链具有[WS₄Ag]重复单元。聚合阴离子链具有扭曲的线性构型，W-Ag-W和Ag-W-Ag角分别为161.37 (2)°和153.548 (12)°。标题配合物与Y、Yb、Eu、Nd、La、Dy、Sm、Lu和Tb的类似物同型。
