An Experimental and Theoretical Investigation of the Ethylene Oligomerization Reactions Catalyzed by Heterocyclic (Pyrazolyl)Imine Fe(II) and Co(II) Complexes

European Journal of Inorganic Chemistry, EarlyView.
Monometallic iron(II) and cobalt(II) complexes derived from potential hemilabile heterocyclic (pyrazolyl)imine catalyze ethylene oligomerization reactions upon activation with either EtAlCl2 or MAO to give predominantly butenes and hexenes. The catalytic activities are largely controlled by the complex structure and stabilization from the coordinated ...

Insights into the Base‐Stabilized Silylene Nature of the IrSi Bond in Ir(III)–(κ2‐NSi) Complexes with 2‐Quinolone and 2‐Pyridone Type Ligands

European Journal of Inorganic Chemistry, EarlyView.
Density functional theory calculations (natural bond orbital and quantum theory of atoms in molecules analyses) on Ir–(κ2‐NSi) complexes with 2‐quinolone and 2‐pyridone derived ligands indicate that the bond is best described as a base‐stabilized silylene. The silicon environment is the key for determining the nature of the IrSi bond.

Is there a "native" band gap in ion conducting glasses?

, 2002
It is suggested that the spectrum of ion site energies in glasses exhibits a band gap, establishing an analogy between ion conducting glasses and intrinsic semiconductors.
