Theoretical Search for Very Short Metal-Actinide Bonds: NUIr and Isoelectronic Systems

摘要

It was recently discovered that platinum can act, in discrete molecular groups, as a chemical analogue to oxygen. For instance the discrete molecular groups CPt, CPt_2, and CPt_3~(2-) were then found to have analogous bonding systems as CO, CO_2, and CO_3~(2-), respectively. These analogues provide an example of the isolobal principle, now without any outside ligands on the Pt atom, a situation described as its "autogenic isolobality". These systems have multiple C-Pt bonds. The isolobal principle of Hoffmann refers to the similar chemical behavior of an sp hybrid and a metal atom with ligands, -ML_n. In "autogenic isolobality" a similar behavior occurs without the ligands, L.
