title: Formation of an infinite 2D-layered water of (H2O)45 cluster in a cryptand-water supramolecular complex: a template effect.
abstract: Structural aspects governing the formation of the water layer in the octaaminocryptand L were examined. Crystallographic results reveal an unprecedented, infinite two-dimensional (2D) layer of water molecules by interconnection of (H2O)45 clusters under confined conditions. This unique 2D layer is basically a template effect of L where the N4 donor sets facilitate the formation of the crown shape water at both ends which, on propagation, generates an infinite through-channel down the c-axis. Thermal analysis, powder X-ray diffraction, and IR studies carried out on L.(H2O)15, 1, support the crystallographic results.
