This volume presents reviews of topical areas in structural determination and structural chemistry, edited from the Proceedings of the 8th Symposium on Organic Crystal Chemistry, held at Poznan-Rydzyna, Poland in 1992.In this volume the definition of organic crystallography is interpreted widely to include factors influencing conformation, packing arrangements, and intermolecular bonding, as well as the determination of the positions and motions of the constituent atoms in molecular structures.An opening chapter introduces the edited proceedings which cover some of the most active areas in the structural determination and structural chemistry of small organic molecules in the crystalline state. The final chapter examines the current concerns of the adherents of organic crystallography and the future role and status of organic crystallography in structural science.The volume is divided into four sections: collection and treatment of diffraction data; crystalline-state reactions; structure correlation and structure-activity relations; and conformation, packing, and bonding in molecular crystals.
