Book Description
This invaluable book distils the research accomplishments of Professor Fred Basolo during the five decades when he served as a world leader in the modern renaissance of inorganic chemistry. Its primary focus is on the very important area of chemistry known as coordination chemistry.Most of the elements in the periodic table are metals, and most of the chemistry of metals involves coordination chemistry. This is the case in the currently significant areas of research, including organometallic homogenous catalysis, biological reactions of metalloproteins, and even the solid state extended structures of new materials. In these systems, the metals are of primary importance because they are the sites of ligand substitution or redox reactions. In the solid materials, the coordination number of the metal and its stereochemistry are of major importance.Some fifty years of research on transition metal complexes carried out in the laboratory of Professor Basolo at Northwestern University is recorded here as selected scientific publications. The book is divided into three different major research areas, each dealing with some aspect of coordination chemistry. In each case, introductory remarks are presented which indicate what prompted the research projects and what the major accomplishments were. Although the research was of the academic, curiosity-driven type, some aspects have proven to be useful to others involved in projects that were much more applied in nature.

Book Description
The application of a multi-component reaction approach has been explored in the synthesis of intricate ligands incorporating the commonly employed ligand motifs bis(2-pyridylmethyl)amine (bPMA) and tris(2-aminoethyl)amine (tren). The synthesis of these ligands demonstrates that multi-component reactions can be an area with high exploratory power in ligand syntheses as they have the potential to afford ligands with a diverse variety of structures by a simple methodology.The coordination chemistry of one bPMA based ligand has been examined with a range of transition metal ions (i.e. MnII, CoII and CuII). The structures of several of these products have been determined by X-ray crystallography and their properties examined by various spectroscopic methods. The complexes are discussed in terms of similarities and differences in the solid state between the different metal ions in combination with different counter ions. Mononuclear and dinuclear complexes, and one case of a 1D coordination polymer were isolated.The spectroscopic properties of copper(II) complexes formed by two analogous tren based ligands were studied. From these studies, it could be concluded that the two ligands formed analogous complexes in both solution and in the solid state. Data on three of the copper(II) tren complexes were collected using synchrotron radiation due to the small size of the isolated crystals. These complexes were found to have trigonal bipyramidal coordination geometry around the mononuclear copper(II) centre. Two isomeric copper(II) nitrate complexes with minor differences in the copper(II) geometries were isolated. In addition, a copper(II) fluoride complex [CuLF]BF4·THF (L = tren based ligand) was studied which interestingly exhibited a very short Cu-F bond, in fact theshortest reported to present time.The copper(II) complexes were further investigated in catalytic oxidation reactions and small ion stabilisation studies. The complexes had poor catalytic activity in catechol oxidation and in oxidative coupling of 2,6-di-tert-butylphenol. However, the bPMA based copper(II) complex showed an initially relatively high catalytic activity in the oxidative coupling reaction, but underwent deactivation. The complexes were not worthy of further investigation in these reactions due to the low catalytic activity. Preliminary results pointed to the fact that the tren based ligands were able to stabilise Cu-OOH species in the solution at low temperatures (-60 and -80 °C). Such complexes are of interest in the elucidation of enzymatic mechanisms of monooxygenases such as peptidylglycine [alpha]-hydroxylating monooxygenases and dopamine [beta]-monooxygenases. These Cu-OOH complexes also demonstrated evidence of partial ligand oxidation upon warming the solutions containing the complexes.Overall a range of ligands structures with intricate structures have been synthesised by a multi-component approach and used to prepare transition metal complexes (CuII, CoII and MnII) which display interesting properties due to the unusual ligand frameworks with large pendant substituents.

Book Description
In recent days large area of inorganic chemistry research is acquired by coordination chemistry due to its interesting and significant properties. Coordination chemistry has always been challenge. Earlier there were mysteries about structure and bonding. The rapid developing field of bio-inorganic chemistry is centered on the study of coordination compounds present in living organisms. Many biologically active compounds are coordination complexes. The similar types of synthesized complexes have served as model of such biologically active compounds. The bio-inorganic chemistry is largely concerned with coordination chemistry.

Book Description
In September 2002, a NATO-ASI was held in Cetraro (CS), Italy on the theme of "Metal-Ligand Interactions in Molecular-, Nano-, Micro-, and Macro-systems in Complex Environments". This event has followed the previous ones held in the same place in 1991, 1994 and 1998. In the present and the previous schools a broad interdisciplinary cross-section of experimental and theoretical researchers, interested in a better understanding of metal-ligand interactions from different viewpoints, was linked together to exchange experience, to review the state-of-the-art, to indicate new techniques and methods, to explore new fields and perspectives. Particular emphasis was given to the problems related with the crossing from molecular systems to nano-, macro-and micro-scale materials and to the effects of the environment on the properties of the molecular systems. The school was organized around lectures and special research seminares given by leading experts in the following fields: • metal clusters • inorganic complexes and materials • surface phenomena • adsorption and catalysis • organic and bio-inorganic systems • ab initio theory • density functional theory • classical and quantum dynamics This volume contains the formal lectures and selected contributed papers and describes the main aspects and problems tackled during the 12 days of the event.

Book Description
Recent advances in machine learning or artificial intelligence for vision and natural language processing that have enabled the development of new technologies such as personal assistants or self-driving cars have brought machine learning and artificial intelligence to the forefront of popular culture. The accumulation of these algorithmic advances along with the increasing availability of large data sets and readily available high performance computing has played an important role in bringing machine learning applications to such a wide range of disciplines. Given the emphasis in the chemical sciences on the relationship between structure and function, whether in biochemistry or in materials chemistry, adoption of machine learning by chemistsderivations where they are important
