A Self-Assembled, Decameric Water Cluster Stabilized by a Cyano-Bridged Copper(II) Complex

Abstract

A self-assembled, decameric water cluster stabilized by a cyano-bridged copper(II) complex was characterized by X-ray diffraction studies, FTIR, and thermogravimetric (TG) and differential scanning calorimetric (DSC) analyses. Every water cluster is connected strongly, via hydrogen bonds, to four cyano nitrogens of a [Fe(CN)6]4- anion. The complex water rings are stable indefinitely at room temperature, and when thermally decomposed, the water loss is irreversible.
