Abstract

Single crystals of 2-CH3CH2C6H4NH36P6O18⋅4H2O are synthesized in aqueous solution by the interaction of cyclohexaphosphoric acid and 2-ethylaniline. This compound crystallizes in the monoclinic system with P21-c space group the unit cell dimensions are: 𝑎=16.2204 Å, 𝑏=10.2205 Å, 𝑐=20.3284 Å, 𝛽=113.243∘, 𝑍=2, and 𝑉=3096.518 Å

. The atomic arrangement can be described by layers formed by cyclohexaphosphate anions P6O6-18 and water molecules connected by hydrogen bonds O–H⋯O. These inorganic layers are developed around bc planes at 𝑥=1-2 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 behaviour and the IR spectroscopic studies of this new cyclohexaphosphate are discussed.
