“Organic crystal chemistry” by Alexander Isakovich Kitaigorodsky is not just a textbook or a reference book, but a real journey into the amazing world of crystals and molecular structures, revealing the secrets hidden in organic chemistry. This book is intended for those who want to understand how and why organic compounds form crystals, what patterns underlie their structure, and how this knowledge is applied in modern science and industry. The author focuses on complex, sometimes mysterious processes of crystallization of organic substances, which he skillfully explains in accessible language, saturated with living examples and vivid illustrations. Kitaigorodsky is not limited to dry theoretical calculations, he introduces the reader to the exciting world of crystals, talking about how their shape, symmetry and properties are related to the molecular structure. The book discusses in detail the methods of studying crystals, their properties and role in the development of new materials, medicines and technologies. This book is especially suitable for students, graduate students, teachers and specialists in chemistry, materials science and pharmaceuticals, as well as anyone interested in structural chemistry and crystallography. The age of readers is from 16 years and older, since the material is submitted taking into account the level of training, but at the same time it retains vitality and fascination, which makes the book attractive for science lovers without specialized education. Themes, raised in "Organic Crystal Chemistry" , is not only the basics of the crystal lattice and methods of its research such as X-ray analysis, But also more profound questions about CM. how the structure affects the properties of substances , how to control crystallization processes and create new materials with specified characteristics. The author emphasizes the importance of crystals in medicine, electronics and energy, which makes the book relevant and modern. The style of Alexander Kitaigorodsky is a combination of scientific accuracy and a lively, understandable presentation. He is able to turn complex concepts into fascinating stories, which makes reading not only informative, but also exciting. His other well-known works, such as Fundamentals of Structural Chemistry and Molecular Architecture, confirm his status as an expert and passionate promoter of science. If you are looking for a book that will help you understand how crystals are born from molecules and why this is important for the development of technology, then the “Organic crystal chemistry” of Alexander Kitaigorodsky will become an indispensable source of knowledge for you. This book will not only expand your horizons, but also inspire new discoveries in chemistry and materials science, opening the door for the reader to the exciting world of molecular beauty and structural harmony.
