title: New pyrazolino- and pyrrolidino[60]fullerenes with transition-metal chelating pyridine substitutents: synthesis and complexation to Ru(II).
abstract: Three pyridine-substituted fullerene adducts, bis(2,2'-bipyridine)(2'-phenyl-5'-(2-pyridinyl)-2'H-[5,6]fullereno(C(60)-I(h))[1,9]pyrazole)ruthenium-bis(hexafluorophosphate) (1), bis(2,2'-bipyridine)(2'-phenyl-5'-(4-(4'-methyl-2,2'-bipyridinyl))-2'H-[5,6]fullereno(C(60)-I(h))[1,9]pyrazole)ruthenium-bis(hexafluorophosphate) (2), and bis(2,2'-bipyridine)(1',5'-dihydro-3'-methyl-2'-(4-(4'-methyl-2,2'-bipyridinyl))-2'H-[5,6]fullereno(C(60)-I(h))[1,9]pyrrole)ruthenium-bis(hexafluorophosphate) (3), have been prepared. The common features for these complexes are the short bridges between the fullerene and the pyridine moieties. [structure: see text]
