Two novel anionic indium phosphites, formulated as [H{sub 3}O][In(HPO{sub 3}){sub 2}] (1) and [C{sub 4}H{sub 12}N{sub 2}][In{sub 2}(HPO{sub 3}){sub 3}(C{sub 2}O{sub 4})] (2), were prepared under hydrothermal conditions by using piperazine (PIP) as a structure-directing agent (SDA). Single-crystal X-ray diffraction analysis reveals that compounds 1 and 2 crystallize in the hexagonal space group P6{sub 3}mc (No. 186) and orthorhombic space group Cmcm (No. 63), respectively. Compound 1, constructed from InO{sub 6} octahedra and HPO{sub 3} pseudo-pyramids, exhibits a rare (3,6)-connected layer structure with kgd (Kagome dual) topology. Compound 2, on the other hand, features a 3D phosphite-oxalate hybrid structure with intersecting 8- and 12-MRs channels. From a topological perspective 2 can be regarded as a (3, 5)-connected binodal net with the Schlaefli symbol (4{sup 2}.6)(4{sup 2}.6{sup 5}.8{sup 3}). Highlights: Black-Right-Pointing-Pointer Two novel indium phosphite and indium phosphite-oxalate hybrid compounds are synthesized. Black-Right-Pointing-Pointer (3, 6)-connected layer structure with kgd topology. Black-Right-Pointing-Pointer (3,5)-connected binodal net with the Schlaefli symbol (4{sup 2}.6)(4{sup 2}.6{sup 5}.8{sup 3}).
