Abstract
Chemical preparation, X-ray characterization, IR spectroscopy, and thermal analysis of a new cyclohexaphosphate, [4-CH3CH2OC6H4NH3](6)P(6)O(18 center dot)8H(2)O, are reported. The atomic arrangement can be described by layers formed by cyclohexaphosphate anions P6O186- and water molecules connected by hydrogen bonds (O-H center dot center dot center dot O). These inorganic layers are developed around bc planes at x = 0 and are interconnected by the H-bonds created by ammonium groups of organic cations. All the hydrogen bonds, the van der Waals contacts, and electrostatic interactions between the different entities give rise to a three-dimensional network in the structure and add stability to this compound. The thermal behavior and the IR spectroscopic studies of this new cyclohexaphosphate are discussed.
