摘要：

Ring opening of thiophenes containing an azo function in 2-position and subsequent dimerization through CC coupling were observed on reaction with [Ru(acac)(2)(CH3CN)(2)] (acac=acetylacetonate) to produce two 1,3,5-hexatriene-linked redox-active azothiocarbonyl chelate systems. Interaction of the non-innocent chelate ligands and of the metals at a nanoscale distance of 1.45nm via the conjugated hexatriene bridge was studied by magnetic and electron spectroscopic measurements in conjunction with DFT calculations, revealing four-center magnetic interactions of this unique setting and weak intervalence coupling after reduction.
