Double Metallocene Nanowires

摘要

Organometallic multidecker sandwich clusters and nanowires have attracted increasing research attention because of their novel structural, electronic, magnetic, and transport properties. Similar to the well-known ferrocene [FeCp_2] (Cp, C_5H_5), a number of multidecker sandwich complexes can be highly stable, for example, TM_nBz_(n+1) (TM = transition metal, Bz = C_6H_6) and TM_nCp_(n+1) complexes, as well as the lanthanide rare earth metal-C_8H_8 complexes. Also, quintuple-decker V_n(BZ)_(n+1) clusters have been synthesized successfully and exhibit an intriguing ferromagnetic property. Subsequent theoretical studies have shown a possible structural transition from achiral D_(6h) to chiral D_2 symmetry in these clusters, and the clusters' magnetic moments increase linearly with size n.
