A Highly Symmetric Ionic Crystal Constructed by Polyoxoniobates and Cobalt Complexes for Preferential Water Uptake over Alcohols

A Highly Symmetric Ionic Crystal Constructed by Polyoxoniobates and Cobalt Complexes for Preferential Water Uptake over Alcohols

Polyoxoniobate was combined with cobalt complexes to produce a novel ionic hybrid compound, where the polyanionic PNb12O40(VIVO)6 and cationic [CoII(pn)3]2+ (pn = 1,2-diaminopropane) densely arrange to offer a quite high symmetry structure. Moreover, it gives a void volume as small as 3.10% within the supramolecular framework and exhibits preferential inclusion of water over alcohols. Interestingly, a gate-opening behavior in the water adsorption isotherm of 1 is observed.
