Abstract

The cluster complex (Me₄N)K₇[{Re₄(µ₃-CCN)₄}(CN)₁₂]·10H₂O (I) is synthesized by the high-temperature reaction of ReI₃ with KCN and subsequent recrystallization from an aqueous solution with the addition of Me₄NI. The anion of complex I contains ligands µ₃-CCN^3– stabilized due to coordination to the triangular faces of the {Re₄} tetrahedral metal cluster. It is shown for [Ni(Еn)₂]²⁺ as an example that the µ₃-CCN^3– ligands are ambidentate and can interact with transition metal cations similarly to the terminal CN groups, affording the coordination polymer [Ni(En)₂(NH₃)₂][{Ni(En)₂}₃{Re₄(µ₃-CCN)₄}(CN)₁₂]·7.5H₂O (II). The structures of complexes I and II are determined by X-ray diffraction analysis (CIF file ССDС nos. 2057450 (I) and 2057451 (II)).

[Ni(Еn)2]2+阳离子与[{Re4(μ3-CCN)4}(CN)12]8-簇阴离子配位的特性

摘要

簇配合物 (Me ₄ N)K ₇ [{Re ₄ (µ ₃ -CCN) ₄ }(CN) ₁₂ ]·10H ₂ O ( I ) 通过 ReI ₃与 KCN的高温反应和随后的重结晶合成从添加 Me ₄ NI的水溶液中提取。配合物I的阴离子包含配体 μ ₃ -CCN ^3–由于与 {Re ₄ } 四面体金属簇的三角形面配位而稳定。以[Ni(Еn) ₂ ] ²⁺为例，μ ₃-CCN ^3–配体是双齿的，可以与类似于端基 CN 基团的过渡金属阳离子相互作用，提供配位聚合物 [Ni(En) ₂ (NH ₃ ) ₂ ][{Ni(En) ₂ } ₃ {Re ₄ ( µ ₃ -CCN) ₄ }(CN) ₁₂ ]·7.5H ₂ O ( II )。复合物I和II的结构由 X 射线衍射分析确定（CIF 文件 ССDС 编号 2057450 ( I ) 和 2057451 ( II )）。
