Abstract

This thesis is concerned with structure, thermodynamic and kinetic aspects of a variety of inclusion compounds which contain small organic guests. The host compounds studied are alkaline-earth metal salts of O,O’-dibenzoyl-(2R, 3R)-tartraric acid (magnesium, calcium and strontium), 1,1’-bis-(4-hydroxyphenyl)cyclohexane (DHPC) and 2,2’-dihydroxy-1,1’-binaphthyl (BINAP). The alkaline-earth metal salts form coordination complexes with 2-methoxyethanol, water or ethanol and the guests act as a part of the coordination sphere of the metal ions. The diol host DHPC preferably forms layer type inclusion compounds with the isomers of picoline, lutidine and xylidine, as well as a number of selected solvents including 1,4-dioxane, DMSO, morpholine, THF and acetone, preferably in channel type inclusion modes. In the latter two classes of inclusion compounds the inclusion is facilitated by the formation of hydrogen bonds from the host hydroxyl moieties to the guests.
