Abstract

The synthesis approach based on the acid-base interaction is used to synthesize 4f/4d heterometallic chalcogenide compounds. By the interaction of the acidic hydrosulfide complex of zirconium \([\text{Cp}'_2\text{Zr}{{(\text{SH})}_{\text{2}}}]\) (Cp′ = η⁵-t-BuC₅H₄) with basic \([\text{Cp}_{2}^{\mathbf{*}}\text{Dy}(\text{allyl})]\) a heterometallic \({{[\text{Cp}'_2\text{Zr}(\mu \text{-S})({{\mu }_{3}}\text{-S})\text{DyCp}_{2}^{\mathbf{*}}]}_{2}}\) complex is obtained, which is the first example of dysprosium–zirconium chalcogenide coordination clusters (1). The structure of the complex is determined by single crystal Xray diffraction. New crystalline modifications of the known sulfide complex of zirconium \({{[\text{Cp}'_2\text{Zr}(\mu \text{-S})]}_{2}}\), being the decomposition product of \([\text{Cp}'_2\text{Zr}{{(\text{SH})}_{\text{2}}}]\) in solution, are also structurally characterized.

镝-锆硫属元素络合物的第一个例子

摘要

基于酸碱相互作用的合成方法用于合成4 f /4 d异金属硫属化物化合物。通过锆的酸性氢硫化物络合物的相互作用\([\text{Cp}'_2\text{Zr}{{(\text{SH})}_{\text{2}}}]\) (Cp' = η ⁵ - t -BuC ₅ H ₄ ) 具有基本的\([\text{Cp}_{2}^{\mathbf{*}}\text{Dy}(\text{allyl})]\)异金属\({{[\text{Cp}'_2\text{Zr}(\mu \text{-S})({{\mu }_{3}}\text{-S})\text{DyCp} _{2}^{\mathbf{*}}]}_{2}}\)络合物，这是镝-锆硫族化物配位簇的第一个例子（1）。复合物的结构由单晶 X 射线衍射确定。已知的锆硫化物复合物的新结晶变体\({{[\text{Cp}'_2\text{Zr}(\mu \text{-S})]}_{2}}\)，即分解\([\text{Cp}'_2\text{Zr}{{(\text{SH})}_{\text{2}}}]\)在溶液中的产物，也具有结构特征。
