New Three-Dimensional (3,4)-Net Zincophosphites Templated by Linear Diammonium Cations: H3N(CH2)5NH3·Zn3(HPO3)4 and β-H3N(CH2)6NH3·Zn3(HPO3)4

Abstract

The mild-condition syntheses, single-crystal structures and properties of H<inf>3</inf>N(CH<inf>2</inf>)<inf>5</inf>NH<inf>3</inf>·Zn<inf>3</inf>(HPO<inf>3</inf>)<inf>4</inf> and β-H<inf>3</inf>N(CH<inf>2</inf>)<inf>6</inf>NH<inf>3</inf>·Zn<inf>3</inf>(HPO<inf>3</inf>)<inf>4</inf> are reported. Both are constructed from (3,4)-nets of ZnO<inf>4</inf> tetrahedra and HPO<inf>3</inf> pyramids, sharing vertices to result in three-dimensional anionic open-frameworks. In both materials, the organic species interacts with the framework by way of N-H⋯O bonds.
