Abstract
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.
