Construction of two-dimensional supramolecular structure containing water tetramer and octamer

The complex [Cd2(phen)4(p-phth)(H2O)2](p-phth) · 10H2O (1) has been synthesized by the reaction Cd(NO3)2 with phen and p-phth (where phen = 1,10-phenanthroline, p-phth = p-phthalic acid) in a solution of ethanol and distilled water. The crystal structure was characterized by X-ray single-crystal diffraction and infrared spectrum. In 1, a novel 2D supramolecular structure was formed, containing water octamer and tetramer.
