The growing world of crystal forms
Abstract
Engineering crystal properties by a choice of adequate molecular building blocks has to cope with the fact that a given molecule can be isolated in many, at times very many, solid forms (single entity crystals, solvates, salts, co-crystals and their polymorphs) each with its own characteristics and properties. Preparation of new crystal forms of a same molecule, and investigation of the relationship among new crystal forms represent not only a further challenge to the solid state chemists, but also an opportunity of modifying properties of crystals with applicative implications (
