A perfect water square in uudd configuration, built from solvent waters has been isolated from a hybrid metal-organic host [Cu(3-aminomethyl)pyridine oxalateOH(2)center dot 2H(2)O](n) under self assembly conditions, stabilizing the supramolecular framework through cooperative hydrogen bonding interactions, a rare occurrence among water clusters. The present findings with detailed crystallographic and theoretical studies add to our knowledge regarding the understanding of the contribution of water clusters to the stability and function of biological assemblies as well as the anomalous properties of water.
