Synthesis, structure and dielectric deuterated effect of a novel organic–inorganic hybrid compound

Abstract

One novel organic–inorganic hybrid compound, (EB-NH 3 + )(18-crown-6)·H 2 PO 4 − ·2H 3 PO 4 ·2.5H 2 O ( 1 ) (EB-NH 3 + = 4-ethoxybenzenammonium; 18-crown-6 = 1,4,7,10,13,16-hexaoxacyclo-octadecane), has been synthesized and characterized by powder X-ray, IR, thermogravimetric analysis and single X-ray structure analysis. In the structure of complex 1 the organic (EB-NH 3 + )(18-crown-6) supermolecular cation sheet and inorganic phosphate anion sheet arrange alternately. Compound 1 and its deuterium product 2 display excellent dielectric property with a huge dielectric permittivity deuterated effect (DEF) of 1649% (200 Hz, 300 K). In the novel organic-inorganic hybrid compound 1, organic supermolecular cation and inorganic phosphate anion sheet arrange alternately. The frequency-dependent and temperature-dependent dielectric constants measurement shows that compound 1 and its deuterium product 2 display excellent dielectric property with a huge dielectric permittivity deuterated effect (DEF) of 1649% (200Hz, 300K). ► We report one organic-inorganic hybrid compound in which the organic (EB-NH 3 + )(18-crown-6) supermolecular cation sheet and inorganic phosphate anion sheet arrange alternately. ► This compound and its deuterium product display a huge dielectric permittivity deuterated effect. ► The huge dielectric DEF is due to the great dielectric response of water molecules.
