A novel hydrogen-bonded microporous framework constructed from two different metal complexes.
A hydrogen-bonded coordination supramolecule, (meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-kappa4N)nickel(II) [N,N-o-phenylenebis(oxamato)-kappa4O,N,N',O']nickelate(II) dihydrate, [Ni(C16H36N4)][Ni(C10H4N2O6)]*2H2O or [Ni(meso-cth)][Ni(opba)]*2H2O, has been prepared and characterized by X-ray crystallographic analysis. The two complex ions, i.e. [Ni(meso-cth)]2+ and [Ni(opba)]2-, are hydrogen bonded to each other, resulting in two-dimensional neutral supramolecular sheets. The sheets stack along the a direction to produce a three-dimensional architecture with one-dimensional channels in which hydrogen-bonded chains of water molecules are included.
