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