Synthesis of Molecular Dodecanuclear Carbon-centered Rhenium Cluster Re12CS17 and its Conducting Properties

The unique dodecanuclear cluster compound Re12CS17 was prepared and studied by X-ray, complex impedance method and density functional theory (DFT). The compound is amorphous, possesses semiconducting properties. Computer simulations showed that the Re and S atoms at the external borders of the neighboring molecules Re12CS17 can form sufficiently strong Re•••S intermolecular bonds, similar to the Mo•••S intermolecular bonds of cuboctahedron Mo6S8 molecules in the Chevrel phases.

Highly Exfoliated Graphite Fluoride as a Precursor for Graphene Fluoride Dispersions and Films

We synthesized highly exfoliated graphite fluoride of approximate composition C2F by treating highly exfoliated graphite with ClF3. The formed material was found to be dispersible in solvents giving 1 to 5 layered fluorinated graphene. Dispersions successfully formed in polar organic solvents capable of establishing hydrogen bonds. The highest stability is achieved in branched alcohols such as tert-butanol. The dispersions may be further processed into thin films by vacuum filtration technique. Also, composite multilayered films of graphene fluoride and graphene may be prepared. (doi: 10.5562/cca1972
