Crystalline hydrate

A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures. Historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the composition without indicating how the water is bound. Per IUPAC's recommendations, the middle dot is not surrounded by spaces when indicating a chem… WebCrystallization from mixed-solvent systems afforded two new crystal structures: a hydrate (7) and an anhydrate (10) (see Scheme 1). Water slurries were performed on dried samples of 4–11 under ambient conditions. Of the eight compounds studied, three (5–7) yielded …
