Experimental and theoretical investigations have provided evidence that the water trimer, tetramer, and pentamers have cyclic, quasi-planar minimum energy conformations. Larger water clusters were expected to have stereo geometries with the hexamer representing the transition from a cyclic to a three-dimensional geometry . On the other hand, infinite onedimensional (1-D) , twod-imensional (2-D) and threedimensional (3-D) water morphologies, typically assembled from basic water clusters, have also been documented. In contrast to the isolated water clusters, the formations and structures of polymeric water still needs more studies.

The design of metal–organic frameworks (MOFs) with voids and channels, usually assembled as porous materials, is an area of great interest. These compounds are able to adsorb, store and release guest molecules. Among other functions, some MOFs can form polymeric magnets, present nonlinear optic (NLO) properties, redox activity, porous magnetic properties, and may perform as selective electric conductors.
Investigations on water clusters have received considerable interest because of their importance for human life, as well as their roles in many biological and chemical processes. As a result, a number of discrete water clusters including trimers , hexamers , octamers , decamers have been found in various coordination polymers. Studies on these ‘‘discrete” water clusters have advanced our knowledge toward understanding the behavior of bulk water .
