Abstract
A novel cadmium cyclohexaphosphate (C5H14N2)(2)Cd2Cl2P6O18.4H(2)O has been prepared and characterized by single-crystal X-ray diffraction, infrared and Raman spectroscopies, thermogravimetric analysis, and cyclic voltammetry. The structure consists of vertex linked of CdO5Cl octahedral and P6O18 rings assembled into a two-dimensional macroanionic layers. Organic double-protonated homopiperazine cations are located between these layers and interact with the framework both electrostatically and via hydrogen bonds of N-HO(Cl).
