Four new hybrid open-framework indium phosphate-oxalates, I, Na[InPO 4(C2O4)0.5]·H2O II, [C2N2H10]0.5[InPO 4(C2O4)0.5] III, [C 3N2H12]2 [In4(HPO 4)6(C2O4)2] ·4H2O IV, [C3N2H12] 0.5[In2(PO4)(HPO4) (C 2O4)]·H2O have been hydrothermally synthesized by using organic amines such as ethylamine, 1,3-diaminopropane and alkali metal ions such as Na+ as the structure-directing agents (SDAs). The structures of these compounds were characterized by single crystal X-ray diffraction. I and II have the same three dimensional (3-D) framework of [InPO4(C2O4)0.5], which consists of InO6 ocathedra linked by inorganic phosphate and organic oxalate anions that generate intersecting 8-membered ring (8-MR) channels. III has similar structural feature with I and II, their frameworks are all built up from layered indiumphosphate linked by oxalate units. While this linkage results in a large 12-MR channel. The structure of IV is built from double-six-rings (D6Rs) building units linked by oxalate units, which contain large circular 16-MR channels. Single crystal X-ray diffraction measurements show that the SDAs are located in their channels of I ∼ IV.
