Synthesis of molecular dodecanuclear carbon-centered rhenium cluster Re12CS17 and its conducting properties

چکیده
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.

Electronic Switch in the Carbon-Centered [Re12CS17(CN)6]n−Nanocluster
An abrupt change in internuclear Re-Re distances between {Re(6)} subunits in the carbon-centered [Re(12)mu(6)-CS(17)(CN)(6)](n-) complexes caused by the change of the oxidation state (n = 6, 8) is first theoretically shown to be possibly controlled by an external electric field. (13)C NMR signal is shown to change over ~400 ppm (~37G) for mu(6)-C atom together with n. Thereby, the metal cluster...
متن کاملSynthesis of Polyaniline/Polyamide composites as membrane and investigation of its properties
Practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. However by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting p...

متن کاملThe Molecular Mechanics Model of Carbon Allotropes
Carbon can form numerous allotropes because of its valency. Graphene, carbon nanotubes,capped carbon nanotubes, buckyballs, and nanocones are well-known polymorphs of carbon.Remarkable mechanical properties of these carbon atoms have made them the subject of intenseresearch. Several studies have been conducted on carbon nanotubes or graphene. In the presentstudy, the molecular mechanics method ...
