Electronic Switch in the Carbon-Centered [Re(12)CS(17)(CN)(6)] 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 [Re(12)mu(6)-CS(17)(CN)(6)](n-) can be considered as a perspective model of a molecular switch.
