"Oxidative coupling of 2-aminopyrimidine with LiOCl produces 5-chloro-2,2\u017D-azobis(pyrimidine) and 2,20-azobis(5-chloropyrimidine) (abcp), both of which were structurally characterized. The symmetrical abcp was used as strongly -accepting mono- and bis-chelate ligand in complexes with [(bpy)2Ru]2+, [(H6C6)ClRu]+, [(Ph3P)2Cu]+ and (OC)3ClRe. The -acceptor capability of abcp results in low-energy MLCT transitions and facile reduction to isolable radical complexes of which the DFT-calculated and structurally characterized dicopper(I) species {(-abcp)[Cu(PPh3)2]2}(PF6) was studied by X- and W-band EPR and the complex {(-abcp)[Ru(bpy)2]2}(PF6)3 at 9.6, 230 and 285 GHz EPR frequency. The results indicate considerable metal\u016Fligand orbital mixing in the singly occupied molecular orbitals." . "K\u00FCmmerer, H. J." . . "599425" . .
