By using different monoamines as the structure-directing agents, three new open-framework zinc phosphite compounds, [C4H10ON]2·[Zn3(HPO3)4] (1), [CH3CH2NH3]2·[Zn3(HPO3)4] (2) and [H2N(CH3)2]2·[Zn3(HPO3)4] (3), have been synthesized under hydro/solvothermal conditions. The three compounds have different (3,4)-connected frameworks constructed from strictly alternating ZnO4 tetrahedra and HPO3 pseudo pyramids. The presence of 12-ring channels in their structures is noteworthy. The removal of organic cations in the free voids of compound 1 by an ion-exchange process will make the structure collapse.

► Three new open-framework zinc phosphites have been synthesized by using monoamines as the structure-directing agents.
► They exhibit different (3,4)-connected frameworks with 12-ring channels.
► The removal of monoprotonated morpholine cations in the structure of compound 1 by an ion-exchange process will make the framework collapse.
