Some selected transition (Cu, Cr, Mn, Fe, Co and Ni) and non-transition (Zn and Pb) metal complexes of arylhydrazones, namely o-hydroxyacetophenone benzoylhydrazone (HBH) and o-mthoxybenzaldehyde benzoylhydrazone (MBH) have been isolated and characterized by a combination of elemental analysis, spectral (UV-Vis., IR, H NMR) and magnetic measurements. Only two divalent metals (Cu and Ni) yield s...

An overview is presented of the methodology and computations of nuclear shielding and spin–spin coupling constants of transition metal complexes. The presented material also includes an outline of relativistic approaches and their applications to heavy transition metals.

Recently synthesized acyclic silylenes have the potential to rival transition metal complexes in performing single site small molecule activation, which is significant because of the need to find cheap and green alternatives to transition metal complexes for this important class of reactions. However, the current computational study, a full quantum chemical investigation with density functional...
