Fullerene-C70, [5,6]-Fullerene-C70

Product Information

C70 fullerene is the fullerene molecule consisting of 70 carbon atoms. It is a cage-like fused-ring structure which resembles a rugby ball, made of 25 hexagons and 12 pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge.The name is a reverence to Buckminster Fullerene, whose geodesic arches these atoms look like. Fullerene-C70 with high virtue graphite at room temperature utilizing creator precious stone iron blocks with installed electrical microprobes. The electrical opposition of Fullerene-C70 demonstrates a base with change to a nebulous protecting stage finish, while graphite remains directing. Nanoindentation demonstrates hardness esteems 220 times bigger for the weight extinguished nebulous stage than for likewise treated graphite. In the course of the most recent years, Fullerene-C70 has been functionalized from multiple points of view, and unadulterated subordinates of even the bigger, more unpredictable carbon circles C76, C84, and as of late likewise C78, have been detached and portrayed. From the gathered group of information, first broad standards of reactivity and selectivity start to develop for these fullerenes, which are generally less symmetric than C60. Vital data is given by different augmentations to higher fullerenes, in which certain isomers are framed with an exceptional selectivity that exceedes that watched for C60. An especially alluring angle is the chirality of specific allotropes and numerous subordinates.

Molecule

The C70 molecule has a D5h symmetry and contains 37 faces (25 hexagons and 12 pentagons) with a carbon atom at the vertices of each polygon and a bond along each polygon edge. Its structure is similar to that of C60 molecule (20 hexagons and 12 pentagons), but has a belt of 5 hexagons inserted at the equator. The molecule has eight bond lengths ranging between 0.137 and 0.146 nm. Each carbon atom in the structure is bonded covalently with 3 others.

C70 can undergo six reversible, one-electron reductions to C6−
70, whereas oxidation is irreversible. The first reduction requires around 1.0 V (Fc/Fc+
), indicating that C70 is an electron acceptor.

Solution

Fullerenes are sparingly soluble in many aromatic solvents such as toluene and others like carbon disulfide, but not in water. Solutions of C70 are a reddish brown. Millimeter-sized crystals of C70 can be grown from solution

Solid

Solid C70 crystallizes in monoclinic, hexagonal, rhombohedral, and face-centered cubic (fcc) polymorphs at room temperature. The fcc phase is more stable at temperatures above 70 °C. The presence of these phases is rationalized as follows. In a solid, C70 molecules form an fcc arrangement where the overall symmetry depends on their relative orientations. The low-symmetry monoclinic form is observed when molecular rotation is locked by temperature or strain. Partial rotation along one of the symmetry axes of the molecule results in the higher hexagonal or rhombohedral symmetries, which turn into a cubic structure when the molecules start freely rotating
