Three novel bismetallacyclopropa[60]fullerene complexes formed via intermediate monometallacyclopropa[60]fullerene diphosphine ligands

Synthesis, Characterization, and Electrochemical Properties of Novel Transition Metal–Fullerene Complexes Containing Di‐ and Tetraphosphane Ligands

“…[12] Now, as a continuation of this research program, we report other types of transition metal-fullerene complexes that contain either the diphosphane ligand trans-1,1Ј-bis(diphenylphosphanyl)ethylene (dppet) or the tetraphosphane ligand N,N,NЈ,NЈ-tetra(diphenylphosphanylmethyl)ethylene diamine (dppeda). It should be noted that although some of the dppet-containing complexes were preliminarily reported in our recent communication, [13] this paper systematically describes both the dppet-and dppeda-containing fullerene complexes and includes new results, such as the crystal structure of [(η 2 -C 60 Pd)(η 2 -C 60 Pt)(dppet) 2 ], the electrochemical properties of [(η 2 -C 60 Pd)(dppet)] 2 and [(η 2 -C 60 Pd)(η 2 -C 60 Pt)(dppet) 2 ], as well as the synthesis and characterization of the dppet-con- [ 2 ] and dppet in a 1:1:2 molar ratio at room temperature in 44 % yield (Scheme 3). Scheme 3. Interestingly, the above-mentioned dinuclear bisfullerene complexes 3-6 can be also prepared by another method in which the [60]fullerene-derived diphosphanes 1 and 2 were used as starting materials.…”

Harnessing the Synergistic and Complementary Properties of Fullerene and Transition-Metal Compounds for Nanomaterial Applications

“…The metals which can be attached in an η 2 fashion to the [5,6] or [6,6] bond of the fullerene cage consist mainly of the zerovalent second- and third-row transition metals or metal clusters such as W, ,, Mo, Pd, − Pt, , Rh, , Ir, Re, and Os, − with only Co , and Ni − represented from the first row. An example of a 1:1 fullerene–metal complex is presented in Figure , showing an Ir complex containing an enantiomeric phosphine ligand, resulting in an optically active compound .…”

Structure and Dynamic Rearrangements of the Pt2dba3 and Pd2dba3 Complexes in Solution

“…Pt 2 dba 3 is a widely utilized source of Pt species for catalysis and a precursor of Pt compounds. Many nanoscale , and bimetallic , catalysts, electrocatalysts, − functional materials, − homogeneous catalysts, − and metal complexes for materials science − can be generated from these materials. Moreover, there are examples of direct use of Pt 2 dba 3 as a catalyst. − However, despite the significance of this compound, its structure has not yet been fully established.…”
