Reaction in solution and in the solid state of 18-crown[6] with Cs2CO3 and 5-substituted isophthalic acids yields the new organic–inorganic complexes 18-crown[6]Cs[OH-isoH] (2), 18-crown[6]Cs[CH3- isoH] (3), 18-crown[6]Cs[Br-isoH] (4), 18-crown[6]Cs[OCH3-isoH] (5), 18-crown[6]Cs[NO2-isoH](6) and 18-crown[6]Cs[tert-Butyl-isoH] (8), which have all been characterized by X-ray diffraction. All compounds except the latter are isomorphous, in spite of the size, shape and chemical nature of the substituent and its ability to form hydrogen bonds.

Abstract
Reaction in solution and in the solid state of 18-crown[6] with Cs2CO3 and 5-substituted isophthalic acids yields the new organic–inorganic complexes 18-crown[6]Cs[OH-isoH] (2), 18-crown[6]Cs[CH3- isoH] (3), 18-crown[6]Cs[Br-isoH] (4), 18-crown[6]Cs[OCH3-isoH] (5), 18-crown[6]Cs[NO2-isoH](6) and 18-crown[6]Cs[tert-Butyl-isoH] (8), which have all been characterized by X-ray diffraction. All compounds except the latter are isomorphous, in spite of the size, shape and chemical nature of the substituent and its ability to form hydrogen bonds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
