Ring opening of thiophenes contg. an azo function in 2-position and subsequent dimerization through C-C coupling were obsd. 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 1.45 nm via the conjugated hexatriene bridge was studied by magnetic and electron spectroscopic measurements in conjunction with DFT calcns., revealing four-center magnetic interactions of this unique setting and weak intervalence coupling after redn. on SciFinder(R)
