Abstract

A racemic complex, (±)-[Co(en)3]·1.5(C5O5)·3H2O (1), has been synthesized and structurally characterized by single-crystal X-ray diffraction method. Structural determination reveals that the 3D supramolecular architecture of 1 is constructed by the subtle combination of intermolecular hydrogen bonding between the (±)-[Co(en)3]3+ cations and croconate dianions (C5O52−) and π⋯π assembling between the croconate dianions. The hydrophilic 1D channels surrounded by polar pore-walls in its 3D network show a water-only absorption property with reversible de-/re-hydration processes which undergo a reversible polycrystalline transformation demonstrated by in situ PXRD measurements.
