Transition-metal complexes based on the 1,3,5-triethynyl benzene linking unit

The synthesis of a unique series of heteromultinuclear transition metal compounds is reported. Complexes 1-I-3-Br-5-(FcC≡C)-C6H 3 (4), 1-Br-3-(bpy-C≡C)-5-(FcC≡C)-C6H 3 (6), 1,3-(bpy-C≡C)2-5-(FcC≡C)-C

Heterotrimetallic M-M′-M″ transition metal complexes based on 1,3,5-triethynylbenzene: Synthesis, solid state structure, and electrochemical and UV-vis characterization. EPR analysis of the in Situ generated associated radical cations

The synthesis of a series of complexes with different organometallic building blocks unsymmetrically arranged around the periphery of a 1,3,5-triethynylbenzene core is discussed. They are accessible by diverse consecutive reaction sequences, which allow the introduction of transition metal units such as Fc, [(tBu2bpy)(CO)3Re], [(η5-C5H5)(Ph3P)2Ru], [(η5-C5H5)(Ph3P) 2Os], and trans-[(Ph3P)2(Cl)Pt] (Fc = (η5-C5H5)(η5-C 5H4)Fe; tBu2bpy = 4,4′-di-tert-butyl-2,2′-bipyridyl). The solid state structures of five complexes have been determined. The electrochemical behavior of the newly synthesized mono-, heterobi-, and heterotrimetallic assemblies have been studied, showing that there is no significant electronic interaction between the respective metal atoms. UV-vis spectroscopic measurements suggest a weak interaction between the appropriate metal atoms. The associated radical cations were in situ generated by stepwise chemical oxidation and characterized by continuous wave electron paramagnetic resonance (EPR) investigations in X-band performed at low temperatures.
