Book Description
This research was to design and successfully engineer crystals using the non-covalent halogen bonding interaction. A halogen bond is an attractive interaction between a positive electrostatic potential on a halogen atom and a negative site on another molecule. Halogen bonds are increasingly recognized as an effective force for the self-assembly of molecules in predictable patterns to produce new materials with certain desirable properties. The research focused on the formation of large planar polyaromatic assemblies of molecules containing halogen bond donor and acceptor sites. The planar polyaromatic compounds were synthesized using multiple Sonogashira Coupling reactions. This is a cross-coupling reaction that forms carbon-carbon bonds between a terminal alkyne and an aryl halide using palladium catalysts. The X-ray crystal structures of the series of iodo- and bromo-phenylethynylphenylethynylpyridines were shown to form self-complementary dimers in the solid state. The perfluoroiodo- and perfluorobromophenylethynylphenylethynyl derivatives, 3-[{4-[(2-bromo-3, 4, 5, 6- tetrafluorophenyl)ethynyl]phenyl}ethynyl]pyridine, 3-[{4-[(2, 3, 4, 5-tetrafluoro-6-iodophenyl)ethynyl]phenyl}ethynyl]pyridine and 2-[{4-[(3-bromo-2, 4, 5, 6-tetrafluoro- phenyl)ethynyl]phenyl}ethynyl]pyridine, formed self-complementary halogen-bonded dimeric units in the solid state. In contrast, 3-[{4-[(2-bromo-4, 5-difluorophenyl)ethynyl]phenyl}ethynyl]pyridine formed a C-H···N hydrogen- bonded dimer.

Book Description
Long-awaited on the importance of halogen bonding in solution, demonstrating the specific advantages in various fields - from synthesis and catalysis to biochemistry and electrochemistry! Halogen bonding (XB) describes the interaction between an electron donor and the electrophilic region of a halogen atom. Its applicability for molecular recognition processes long remained unappreciated and has mostly been studied in solid state until recently. As most physiological processes and chemical reactions take place in solution, investigations in solutions are of highest relevance for its use in organic synthesis and catalysis, pharmaceutical chemistry and drug design, electrochemistry, as well as material synthesis. Halogen Bonding in Solution gives a concise overview of halogen bond interactions in solution. It discusses the history and electronic origin of halogen bonding and summarizes all relevant examples of its application in organocatalysis. It describes the use of molecular iodine in catalysis and industrial applications, as well as recent developments in anion transport and binding. Hot topic: Halogen bonding is an important interaction between molecules or within a molecule. The field has developed considerably in recent years, with numerous different approaches and applications having been published. Unique: There are several books on halogen bonding in solid state available, but this will be the first one focused on halogen bonding in solution. Multi-disciplinary: Summarizes the history and nature of halogen bonding in solution as well as applications in catalysis, anion recognition, biochemistry, and electrochemistry. Aimed at facilitating exciting future developments in the field, Halogen Bonding in Solution is a valuable source of information for researchers and professionals working in the field of supramolecular chemistry, catalysis, biochemistry, drug design, and electrochemistry.

Book Description
Molecular Crystals and Molecules deals with some of the problems of molecular crystallography and certain aspects of molecular structure. This book is composed of eight chapters that specifically cover the significant progress of conformational research. The opening chapter describes the structure of crystals considering the close-packing principle, disorder elements, and binary systems. The next two chapters examine the calculation of crystal lattice energy and dynamics. These topics are followed by discussions on the molecular movement, structural, and thermodynamic aspects of crystals. The final chapters look into the parameters for conformational calculations of molecules, macromolecules, and biopolymers. This book will be of great value to physical chemists and researchers who are interested in crystal and molecular structure.

Book Description
The field of crystal engineering concerns the design and synthesis of molecular crystals with desired properties. This requires an in-depth understanding of the intermolecular interactions within crystal structures. This new book brings together the latest information and theories about intermolecular bonding, providing an introductory text for graduates. The book is divided into three parts. The first part covers the nature, physical meaning and methods for identification and analysis of intermolecular bonds. The second part explains the different types of bond known to occur in molecular crystals, with each chapter written by a specialist in that specific bond type. The final part discusses the cooperativity effects of different bond types present in one solid. This comprehensive textbook will provide a valuable resource for all students and researchers in the field of crystallography, materials science and supramolecular chemistry.
