Synthesis and Characterization of Tetrakis(4‐oxo‐piperidinium ethylene acetal) Bis Sulfate Hexahydrate

Chemical preparation, x-ray characterization, IR spectroscopy and thermal analysis of a new sulfate (C 7 H 12 O 2 NH 2 ) 4 (SO 4 ) 2 .6H 2 O, are reported. The atomic arrangement can be described by layers formed by sulfate anions (SO -2 4 ) and water molecules connected by hydrogen bonds O-H…O. These inorganic layers are developed around ab planes at z = 0 and z = 1/2 and are interconnected by the H -bonds created by organic groups. 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 behaviour and the IR spectroscopic studies of this new sulfate are discussed.
