The vibrational and electronic properties of a new class of organometallic sandwich molecules have been studied using first principles density functional techniques (DFT). Spectral properties as well as the HOMO-LUMO gap energy in molecules containing up to eight C6 layers have been calculated. S. L. Kuzmin and W. W. Duley show that infinite chains should have excellent metallic properties. These molecules are promising for nanoelectronic applications, due to their predicted high stability, conductivity, and magnetic properties (pp. 297–308).
