Role of crystallization water molecules on hydrogen-bonded structures and dielectric phase transitions in amino trimethylene phosphonic acid-based crystals

Abstract

Three hydrogen-bonded organic salts, (HTBA)2(H4ATMP)•(H2O)3 (1), (HTBA)6(H3O)(H2.5ATMP)2•(H2O)2 (2) and (HTBA)6(H3ATMP)2•H2O (3), were synthesized by combining different molar ratios of amino trimethylene phosphonic acid (H6ATMP) and tert-butylamine (TBA). There are three-dimensional hydrogen-bonded networks in 13. The crystallization water molecules that are loosely trapped in the supramolecular hydrogen-bonded networks in 1 and 2 undergo order-disorder transitions whose dynamic changes are supposed to be responsible for the dielectric transitions and relaxations.
