This book was released on 2013 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bidentate, tetradentate, and hexadentate ligands, with N2, N4, and S2N4 donor sets were complexed with Cu(II) and Ni(II) to form chiral and achiral chelates in an attempt to prepare complexes that allowed for the access of multiple oxidation states through electrochemical methods. The bidentate ligands were prepared from pyrrole-2-carboxaldehyde and chiral and achiral amines and anilines, and were complexed with the desired metal in a 2:1 ratio, with chiral ligands resulting in chiral complexes. Analogous ligands with N4 coordination spheres were also prepared using pyrrole-2-carboxaldyhyde and various diamines, and were complexed in a 1:1 fashion. The tetradentate ligands were prepared using vinylpyridine and chiral piperazine derivatives to form both enantiomers of the chiral complexes, as well as similar non-chiral mono and dinuclear complexes using achiral derivatives of piperazine and homopiperazine. The hexadentate ligands were synthesized from 2-hydrazinopyridine and alkyl and aryl bridged dithio-diketo precursors, which were prepared using either a N,N,N-triethyl-N-(propan-2-onyl)ammonium or N,N,N-triethyl-N-(phenylethan-2-onyl)ammonium chloride salt and a range of dithiols. Synthetic, crystallographic, and absorption data will be presented as well as circular dichroism (CD) data for the chiral complexes and magnetic data for the dinuclear complex. Complexes were also characterized using electrochemistry and ESR.

Book excerpt: In chemistry, a complex, also called a "coordination compound" or "metal complex", is a structure consisting of a central atom or molecule connected to surrounding atoms or molecules. Originally, a complex implied a reversible association of molecules, atoms, or ions through weak chemical bonds. As applied to coordination chemistry, this meaning has evolved. Some metal complexes are formed virtually irreversibly and many are bound together by bonds that are quite strong. Copper is a transition metal, which in the zero oxidation state has an electron configuration of [Ar]4s24p63d9. Copper is found in three different oxidation states: Cu(I), Cu(II), and Cu(III). Copper (I) atoms have 10 d electrons. Cu(I) complexes being d10 have no Jahn-Teller distortion. Cu (I) complexes are diamagnetic and typically colorless. If a Cu(I) complex is colored, the color is a result of a charge transfer band or an internal transition in a ligand. In the copper(II) oxidation state, the metal has 9 d electrons. Jahn- Teller distortion causes a splitting of eg and t2g orbitals. Most Cu(II) complexes are square planar for this reason. Usually observed in the electronic spectra of Cu(II) complexes is a single broad, poorly resolved band envelope. This envelope is typical of Cu(II) complexes in tetragonal complexes. These complexes are generally blue or green because of an absorption band in the 600-900 nm region of the spectrum. Reproducing complex biological reactivity within a simple synthetic molecule is a challenging endeavor with both intellectual and aesthetic goals. The sequence of examining biological reactivity, creating similar chemical architectures, and determining functional reaction conditions for model systems is a process that allows the biological code of reactivity to be deciphered. In the past years the report on the crystal structures of type 3 copper enzymes (e.g. catechol oxidase, hemocyanins, and tyrosinase), as too type 2 - type 3 copper enzymes (e.g. ascorbate oxida.
