Abstract

Three-layered zinc phosphites containing single monoamine molecules with different roles have been synthesized using hydro(solvo)thermal methods and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and infrared spectroscopy. Compound 1, (C8H17NH 3)4Zn3(HPO3)5 · 3H2O, consists of 20-ring layer structures sandwiched by water molecules and protonated tert-octylamine molecules. The structure of Zn(C 8H17NH2)(HPO3) (compound 2) is composed of 4.82 network structures, wherein the tert-octylamines are coordinated to the Zn atom as pendant groups. Compound 3, (C8H 17NH3)2Zn4(C8H 17NH2)(HPO3)5, was prepared in which the amine plays a dual role as both a ligand and a countercation. In addition, compound 1 is the first layered metal phosphite with large 20-ring windows. This group of substances represents the first example of the preparation of compounds in which the reactivity of incorporated single amine molecules is varied by adjusting the synthesis conditions.
