This paper reports the synthesis, characterization, and some properties of transition metal–fullerene complexes containing trans ‐1,1′‐bis(diphenylphosphanyl)ethylene (dppet, trans ‐Ph 2 PCH=CHPPh 2 ) and N , N , N ′, N ′‐tetra(diphenylphosphanylmethyl)ethylene diamine (dppeda, [(Ph 2 PCH 2 ) 2 NCH 2 ] 2 ), including [(η 2 ‐C 60 M)(dppet) 2 ] (M = Pt 1 , Pd 2 ), [(η 2 ‐C 60 M)(dppet)] 2 (M = Pt 3 , Pd 4 ), [(η 2 ‐C 60 Pd)(η 2 ‐C 60 Pt)(dppet) 2 ]( 5 ), [(η 2 ‐C 60 Pd)(η 2 ‐C 70 Pd)(dppet) 2 ] ( 6 ), [(η 2 ‐C 70 Pd)(dppet)] 2 ( 7 ), [(η 2 ‐C 60 M)(dppeda)] (M = Pt 8 , Pd 9 ), and [(η 2 ‐C 60 M) 2 (dppeda)] (M = Pt 10 , Pd 11 ). Interestingly, while complexes 1 , 2 , 8 , and 9 are the first examples of metallacyclopropafullerene diphosphane ligands containing fullerene cores, complexes 3 – 7 , 10 , and 11 are the first group 10 metal‐containing, dumbbell‐shaped bisfullerenes. All the complexes 1 – 11 were characterized by elemental analysis, spectroscopy, and, particularly for 4 and 5 , by X‐ray crystallography and cyclic voltammetry. Pathways for the formation of 1 – 11 are suggested. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
