摘　　要：Two new open-framework gallium phosphites formulated as （C2N2HI0）o.sGa2（OH）（H20）（HPO3）3（I） and （C3N2Hs）2（C3N2H6）Gas（H20）6（HPO3）14（2） were hydrothermally synthesized in the presence of ethylenediamine（en） and imidazole as structure directing agents（SDA）, respectively. Structural analyses reveal that the 3D structures of compounds I and 2 are both built up from the linkage ofGaO6, GaOs（H20） and HPO32 units by sharing vertices. The structure of compound 2 is constructed from well-known 4.6.12-net connecting layers in the AAAA stacking se- quence, which are oenetrated bv the 1D Ga--O--P chains to form a 3D pillared-layered structure.Two new open-framework gallium phosphites formulated as （C2N2HI0）o.sGa2（OH）（H20）（HPO3）3（I） and （C3N2Hs）2（C3N2H6）Gas（H20）6（HPO3）14（2） were hydrothermally synthesized in the presence of ethylenediamine（en） and imidazole as structure directing agents（SDA）, respectively.
