Nanoscale atoms in solid-state chemistry
We describe a solid-state material formed from binary assembly of atomically precise molecular clusters. [Co6Se8(PEt 3)6][C60]2 and [Cr 6Te8(PEt3)6][C60] 2 assembled into a superatomic relative of the cadmium iodide (CdI2) structure type. These solid-state materials showed activated electronic transport with activation energies of 100 to 150 millielectron volts. The more reducing cluster Ni9Te6(PEt3) 8 transferred more charge to the fullerene and formed a rock-salt-related structure. In this material, the constituent clusters are able to interact electronically to produce a magnetically ordered phase at low temperature, akin to atoms in a solid-state compound.
