Abstract
Two new open-framework gallium phosphites formulated as (C2N2H10)0.5Ga2(OH)(H2O)(HPO3)3(1) and (C3N2H5)2(C3N2H6)Ga8(H2O)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 1 and 2 are both built up from the linkage of GaO6, GaO5(H2O) and HPO3 2− units by sharing vertices. The structure of compound 2 is constructed from well-known 4.6.12-net connecting layers in the AAAA stacking sequence, which are penetrated by the 1D Ga-O-P chains to form a 3D pillared-layered structure.
