Structural, Vibrational, Thermal, and Electrochemical Studies of a Cyclohexaphosphate Complex, (C 5 H 14 N 2 ) 2 Cd 2 CL 2 P 6 O 18 .4H 2 O.

A novel cadmium cyclohexaphosphate (C5H14N2)2Cd2Cl2P6O18.4H2O 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 P6O18rings 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–H···O(Cl).
