This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the structures and the magnetic properties of the first row transition metal complexes containing open-chain diazine (N-N) moieties. The purpose of the research is to establish a magnetostructural correlation involving the N-N single bond bridge and to investigate the coordination chemistry of open-chain diazine ligands to the first row transition metal ions. A relevant literature search is presented in Chapter 1. -- Chapter 1 describes a general introduction to magnetic exchange in polynuclear copper complexes and a general review of the coordination chemistry of diazine (N2) bridged complexes. In Chapter 2, seventeen dicopper(II) complexes with five open-chain diazine ligands (PAHAP, PMHAP, PHMAP, PHAAP and PYPZ) are reported, in which the two copper(II) centers are bridged by a single N-N bond only. The X-ray structures of one ligand and twelve dinuclear copper(II) complexes were determined. Changing the ligands, together with varying the coligands leads to a situation where the dihedral angle between the copper planes can be varied from 75° to 168.5°. For small angles (less than 80°) ferromagnetic coupling prevails, whereas at larger angles antiferromagnetic exchange is observed between the copper(II) centers. The exchange integrals (-2J) vary from -24.4 to 210 cm−1. This is associated with the degree of alignment of the nitrogen p orbitals in the diazine bridge, and is supported by molecular orbital calculations on the complexes and appropriate models. Chapter 3 deals mainly with dinuclear copper(II) complexes containing two ligands bridging two metal centers. The dinuclear copper(II) complexes containing two N-N single bonds have no or very weak coupling because of orbital orthogonality and the twisting of the two copper planes around these two N-N single bonds. A dicopper complex containing mixed diazine bridges (pyridazine/N-N) shows weak antiferromagnetic coupling, and since the diazine unit in the aromatic ring system bridges two copper centers in an orthogonal manner, this net antiferromagnetic coupling occurs only through the open-chain diazine bridge. A tetranuclear copper complex contains two pairs of dicopper(II) centers bridged orthogonally by two μ2-1,1-azide anions with each pair of copper(II) centers bridged by one N-N single bond and one μ2-1,1-azide with a 119° azide bridge angle. The dihedral angle about the N-N single bond is 54°, which indicates either no coupling or weak ferromagnetic coupling via such a bridge. Therefore, the strong antiferromagnetic coupling (-2J = 246 cm−1 ) occurs only through the μ2-1,1-azide bridges between each pair of copper(II) centers, giving the first genuine example contradicting the spin polarization mechanism associated with azide bridges. In Chapter 4, a series of spiral-like dinuclear complexes of Mn(II), Fe(II), Fe(III), Co(II), Co(III) and Ni(II) ions containing three N-N single bonds with a formula [L3M2].(X)n.mH2O (L = PAHAP, PZHPZ; X = CIO4 or NO3; n = 4, 6) and a seven-coordinate Fe(III) complex are discussed. The X-ray structures of six of these complexes have been determined. Variable-temperature magnetic properties, electrochemistry and spectra are discussed. Chapter 5 discusses the synthesis, structural and magnetic properties of some mononuclear and polynuclear first row transition metal complexes of the open-chain diazine ligands. The X-ray structures of eight complexes were determined. Two new coordination modes for open-chain diazine ligands have been found. In the last chapter, a general conclusion about coordination modes, magnetostructural correlations, etc. of the open-chain diazine complexes is made.

Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Available in PDF, EPUB and Kindle. Book excerpt: From chemistry to solid state physics to biology, the applications of Electron Paramagnetic Resonance (EPR) are relevant to many areas. This unified treatment is based on the spin Hamiltonian approach and makes extensive use of irreducible tensor techniques to analyze systems in which two or more spins are magnetically coupled. This edition contains a new Introduction by coauthor Dante Gatteschi, a pioneer and scholar of molecular magnetism. The first two chapters review the foundations of exchange interactions, followed by examinations of the spectra of pairs and clusters, relaxation in oligonuclear species, approaches to infinite lattices, and how EPR can provide firsthand information on spin dynamics. Subsequent chapters explore experimental data, magnetically coupled systems, low-dimensional materials, and the use of EPR to characterize excitons and exciton motion. More than 200 figures and tables appear throughout the book, which concludes with a pair of helpful appendices.

Book excerpt: By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.
