Three new hybrid open-framework indium phosphate-oxalates,Ⅰ, Na[InPO4(C2O4)0.5]·H2OⅡ, [C2N2- H10]0.5[InPO4(C2O4)0.5]Ⅲ, [C3N2H12]0.5[In2(PO4)(HPO4)(C2- O4)]·H2O have been hydrothermally synthesized by using organic amines such as ethylamine, 1,3-diaminopropane and alkali metal ions such as Na+ as structure-directing agents (SDA). The structures of these compounds were character-ized by single crystal X-ray diffraction. The structure of Ⅰ consists of InO6 octahedra that are linked by phosphate and oxalate groups to generate a three-dimensional framework with intersecting 8-membered ring (MR) channels parallel to the [100] and [010] directions. The structure of Ⅱ is similar to that of I except that its guest species are protonated ethylamines. Ⅲ is built from indiumphosphate dou-ble-six-rings second building units linked by oxalate units, resulting in large circular 16 MR channels. Single crystal X-ray diffraction measurements show that the SDA of Ⅰ—Ⅲ are located in their channels. Crystal data for these three indium phosphate-oxalates are as follows: Ⅰ, triclinic, space group: P-1 (No. 2), a = 5.5662(17)? b = 6.454(2)? c = 8.966(3)? a = 102.609(4)? b = 107.319(3)? g = 94.426(4)? V = 296.56(16)?, Z = 2, M = 294.81, rcalcu = 3.301 g/cm3, R1 = 0.0275, wR2 = 0.0731. Ⅱ, triclinic, space group: P-1 (No. 2), a = 5.653(4)? b = 6.627(4)? c = 9.391(8)? a = 70.788(8)? b = 75.836(12)? g = 89.681(9)?
