Cyclohexane-based polyaminopolyalcohols (PAPAs) such as 1,3-diamino-1,2,3-trideoxy-cis-inositol (daci) have been prepared by hydrogenation of suitable aromatic precursors. The pentanuclear complex [Cu5(daci)4(H–2daci)2](SO4)3·18H2O (C3) revealed antiferromagnetic and ferromagnetic interactions between the CuII centers with an S = 3/2 ground state. The microporous structure of C3 exhibited a dehydration/rehydration reaction with an entirely amorphous dehydrated phase at 150 °C and a completely reversible rehydration process at 30 °C. The potential of PAPA ligands for forming polynuclear complexes and supramolecular, hydrogen-bonded networks is discussed.
