Structure and bonding in [L]M(µ-CCR)2M[L] and [L]M(µ-RC4R)M[L]: Requirements for C-C coupling

Abstract

A theoretical analysis of [L]M(µ-CCR)2M[L] and [L]M(µ-RC4R)M[L], where M represents selected elements from the main group, transition metals, lanthanides and actinides, shows how the central (µ-CCR)2 and (µ-RC4R) units reorganize as M traverses across the periodic table. In this context transition metal and actinide complexes are similar in nature while lanthanide and main group complexes show similarity. The ground state electronic configuration and thus the metal oxidation state control these striking differences. An effective way to stabilize +3 oxidation state of thorium in a metallacycle complex is shown for the first time. A strategy is made to make a cross connection between two sets. The approach used here lends itself to obvious extensions.
