摘要

在不同的反应条件下，研究了 1,3-二磷酸复合物 [Cp'''Co(η4-P2C2tBu2)]（Cp'''= Cp(tBu)3, 1）与 Ag[Al{OC(CF3)3}4] (Ag[TEF]) 和 [LAu][TEF] (L = (THT)2, (THT)PPh3) 的反应。根据反应物的化学计量、反应时间和温度的不同，单体[{(Et2O)Ag}{Cp'''Co(µ,η4：η1:η1-P2C2tBu2)}][TEF] (4) 和 [Au{Cp'''Co(η4:η1-P2C2tBu2)}2][TEF] (6)，二聚体 [{(Et2O)Ag}2{Cp'''Co(µ,η4：η1:η1-P2C2tBu2)}]-2[TEF] (3)、三聚体[Au3{Cp'''Co(η4:η1:η1-P2C2tBu2)}4]-3[TEF] (7)和[(η1-Ph3)2Au3{Cp'''Co(η4：η1:η1-P2C2tBu2)}2]-3[TEF] (8)，并实现了一维聚合物[Ag{Cp'''Co(η4:η1:η1-P2C2tBu2)}]n[TEF]n (2)。DFT 计算为 2、3 和 4 的组装过程中聚合物的形成提供了更多信息。所有化合物在固态时都通过 X 射线晶体学进行了表征，在溶液中则通过多核核磁共振谱和质谱进行了表征。

Controlled aggregation of a 1,3-diphosphacyclobutadiene complex in the coordination sphere of Ag(I) and Au(I) ions

Reactions of the 1,3-diphosphete complex [Cp'''Co(η⁴-P₂C₂tBu₂)] (Cp''' = Cp(tBu)₃, 1) with Ag[Al{OC(CF₃)₃}₄] (Ag[TEF]) and [LAu][TEF] (L = (THT)₂, (THT)PPh₃) were studied under various reaction conditions. Depending on the stoichiometry of the reactants, reaction time and temperature involved, a selective formation of the monomers, [{(Et₂O)Ag}{Cp'''Co(µ,η⁴:η¹:η¹-P₂C₂tBu₂)}][TEF] (4) and [Au{Cp'''Co(η⁴:η¹-P₂C₂tBu₂)}₂][TEF] (6), the dimer [{(Et₂O)Ag}₂{Cp'''Co(µ,η⁴:η¹:η¹-P₂C₂tBu₂)}]·2[TEF] (3), the trimers [Au₃{Cp'''Co(η⁴:η¹:η¹-P₂C₂tBu₂)}₄]·3[TEF] (7) and [(η¹-PPh₃)₂Au₃{Cp'''Co(η⁴:η¹:η¹-P₂C₂tBu₂)}₂]·3[TEF] (8), and the one-dimensional polymer [Ag{Cp'''Co(η⁴:η¹:η¹-P₂C₂tBu₂)}]_n[TEF]_n (2) was realized. DFT calculations provided additional insight into the formation of the polymeric species during the assembling process of 2, 3 and 4. All compounds were characterized in the solid state by X-ray crystallography and in solution by multinuclear NMR spectroscopy and mass spectrometry.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
