Book Description
New crystalline materials (organic, inorganic, hybrid) are promising for various applications, including electrical, piezoelectric, ferroelectric, magnetic, and catalytic processes. In addition, given their remarkable structural richness, these materials exhibit several interesting physical properties, such as ionic conduction, ion exchange, and others. Crystal growth, morphology, and grain size are factors influencing these physical properties. This book examines methods of synthesis of the most common crystalline materials and describes nucleation and crystal growth of various materials.

Book Description
The goal of the series Physics and Chemistry of Materials with Layered Structures is to give a critical survey of our present knowledge on a large family of materials which can be described as solids containing molecules which in two dimensions extend to infinity and which are loosely stacked on top of each other to form three dimensional crystals. Of course, the physics and chemistry of these crystals are specific chapters in ordinary solid state science, and many a scientist hunting for new phenomena has in the past been disappointed to find that materials with layered structures are not entirely exotic. Their electron and phonon states are not two dimensional, and the high hopes held by some for spectacular dimensionality effects in superconductivity were shattered. Nevertheless, the structural features and their physical and chemical consequences singularize layered structures sufficiently to make them a fascinating subject of research. This is all the more true since they are met in insulators and semiconductors as well as in normal and superconducting metals. Although for the time being the series is intentionally limited to cover inorganic materials only, the many known organic layered structures may well be the subject of future volumes. Among the noteworthy peculiarities of layered structures, we mention specific growth mechanisms and crystal habits. Polytypism is very common and it is fasci nating indeed to find up to 240 different polytypes in the same chemical substance.

Book Description
There is no doubt that in the development of the Physics and Chemistry of Solids during the last fifteen years, the very important place taken by low-dimensional compounds will be remembered as a major event. Dealing very widely at the beginning with two-dimensional structures and intercalation chemistry, this theme progressively evolved as the synthesis of one-dimensional conductors increased, along with the observation of their remarkable properties. Beyond the classical separation of the traditional disciplines, essential progress has stemmed each time from the concerted efforts of, and overlapping between, chemists, experimental physicists, and theoreticians. This book is a synthetic approach which aims to retrace these united efforts. The observation and characterization of charge density waves in their static or dynamic aspects have been the main points to attract the interest of researchers. Two broad categories of compounds have been the material basis of these observa tions: transition-metal polychalcogenides and either condensed-cluster phases or bronze-type compounds. These families are referred to throughout the various chapters of this book, thus illustrating the continuous progress of concepts in this domain and, at the same time, providing the first synthetic and exhaustive view of this group of materials.

Book Description
Hot Topics in Crystal Engineering covers the design and synthesis of single crystalline solid-state materials, their properties and applications, focusing on the understanding and use of intermolecular interactions that constitute single crystalline materials. Many of the most modern materials, such as metal-organic frameworks (MOFs) capable of gas storage and separation, and selective entrapment of harmful substances, are the result of the rational use of crystal engineering. Topics covered in this work highlight breakthroughs in this rapidly developing field. This work offers a carefully chosen cross-section of the latest developments, some in their early infancy and some covered for the first time. Provides comprehensive and authoritative articles, giving readers access to a wealth of information to fully support their research and activities Covers the latest developments in crystal engineering, including topics which are in their early infancy Written by leading international experts

Book Description
The present work focuses on the synthesis, crystal structure determination, electrochemical and luminescence studies of thienyl-substituted methoxides of alkali, tin(II) and rare earth metals. The first part is devoted to the synthesis, NMR and crystallographic investigations of the new products. To correlate structural and stereoelectronic effects on the molecular geometry, a series of rare earth metal alkoxides was prepared. The second part deals on the electrochemical properties of the novel compounds. The cyclic voltammograms are dominated by the oxidation wave of the thiophene groups. No reduction or oxidation of the metal centres bas been noticed. Contrarily to the other compounds, the repetitive cycling ofpotentials ofHO-C(CgHsS2)3 (1), {Nd[OC(CgHsS2)3]3(thf)3} . thf (10) and Er[OC(CgHsS2)3]3(thf) (11) leads to the formation of electroactive polymeric film. The third part concerns the luminescence properties of the novel compounds. The UV-Vis absorption spectra are dominated by the organic ligands. The emission spectra of the potassium, sodium and yttrium compounds reveal broad bands attributed to the [Py* → Py] transitions of the aromatic ligands. Furthermore, the luminescence spectra of the Nd3+ and Sm3+ alkoxides exhibit an energy transfer ("antenna effect") from the Iigand to the lanthanide centre.
