Crystalline structure definition chemistry
WebMany organic molecules, as well as inorganic molecules, form crystals that incorporate water into the crystalline structure without chemical alteration of the organic molecule ( water of crystallization ). The sugar trehalose, for example, exists in both an anhydrous form ( melting point 203 °C) and as a dihydrate (melting point 97 °C).
