We develop a general procedure to analyse the pre-edges in 1s x-ray absorption near edge structure (XANES) of transition metal oxides and coordination complexes. Transition metal coordination complexes can be described from a local model with one metal ion. The 1s 3d quadrupole transitions are calculated with the charge-transfer multiplet program. Tetrahedral coordination complexes have more in...

Context & Scale This review aims to bridge the fields of inorganic molecular chemistry, electrocatalysis, lithium-ion batteries, and chemical physics of oxides by introducing a unifying concept linking the electronic structures and electrochemical properties of transition metal oxides and complexes. In this work, by reviewing broad literature on the redox behavior of a number of Ni, Co, Fe, and...

Schiff bases and their metal complexes are very important in medicinal and pharmaceutical fields because of their wide spectrum of biological activities. Transition metal complexes derived from the Schiff base ligands with biological activity have been widely studied. A series of Ni (II) complexes were prepared by the reaction of salicyldimine with Nickel Oxide at room temperature. The chemical...

2-Phenyl-N,N'-bis(pyridin-4-ylcarbonyl)butanediamide ligand with a series of transition metal complexes has been synthesized via two routes: microwave irradiation and conventional heating method. Microwave irritation method happened to be the efficient and versatile route for the synthesis of these metal complexes. These complexes were found to have the general composition M(L)Cl2/M(L)(CH3COO)2...

Invited for this month's cover is the group of Prof. F. Matthias Bickelhaupt. The cover picture illustrates the authors' quantum chemical finding that π electrons can significantly bend otherwise linear d(10)-ML2 complexes through backbonding. For more details, see the Full Paper on p. 106 ff.

Several ferrocenylalkynes have been prepared and their reaction with dicobalt octacarbonyl led to the formation of [Co2(CO)6(μ-η 2 : η-ethynylferrocene)] 1, [Co2(CO)6(μ-η 2 : η-1,4-bis(ferrocenyl)butadiyne)] 2, [(Co2(CO)6)2(μ-η : η,μ-η : η-1,4-bis(ferrocenyl)butadiyne)] 3, [Co2(CO)6(μ-η 2 : η-1-ferrocenylethynyl-2-hydro-1,2-dihydro[60]fullerene)] 4, [Co2(CO)6(μ-η 2 : η-1,1’-bis(phenylethynyl)fe...
