Chapter 1 provides an introduction to metalloenzymes that either feature active sites containing Ni-thiolate ligation or utilise phenoxyl radicals to perform their catalytic function, with a particular emphasis on the enzymatic active sites of Ni-containing superoxide dismutase (Ni SOD), [NiFe] hydrogenase and galactose oxidase. Studies concerning low molecular weight complexes of each active site are reviewed and their relevance with respect to enzyme function discussed. Details of the project outline conclude the chapter.

Abstract:

Following the discovery that a single molecule can behave as a magnet, the field of research on magnetism has become of great interest to scientists. A large number of polynuclear compounds have been produced and studied worldwide over the past two decades, in an effort to obtain better single molecule magnets (SMMs). The synthesis of such compounds involves mainly first row transition metals and a wide range of bridging ligands.

Abstract:

The existence of complexes of that display non-innocence has been of interest in the field of coordination chemistry since the investigations of square-planar dithiolene complexes of the late transition metals in the 1960s. The ligands used in these systems are termed “non-innocent” when bound to a number of the late transition metals, because the orbital energy levels are similar to those of the central metal ion. This allows there to be significant electron delocalisation over the complex with the potential for the complexes to exist in a number of electronic states due to the combined elect

A library of variously-substituted dipyrrins and their first-row transition metal (Mn, Fe, Cu, Zn) complexes have been synthesized, and the effects of peripheral substituents on the spectroscopic, electrochemical, and structural properties of both the free-base dipyrrins and their metal complexes has been explored. The optical and electrochemical properties of the free dipyrrins follow systematic trends; with the introduction of electron-withdrawing substituents in the 2-, 3-, 5-, 7-, and 8-positions of the dipyrrin, bathochromic shifts in the absorption spectra are observed, oxidation becomes

Early transition metal hydrides are currently of great interest; they are intermediates in catalytic processes, and have demonstrated ability to activate small molecules. While these complexes are traditionally supported by cyclopentadienyl-type ancillary ligands, current efforts are focused on alternative architectures. In particular, chelating mixed-donor ancillary ligands are currently employed for the synthesis of metal hydride complexes.
