Abstract	A new inorganic-organic hybrid structure has been synthesized hydrothermally in the iron phosphate oxalate family using 1,4-bis(3-aminopropyl)piperazine as the structure-directing agent. Crystal data for I, [C10N4H28][Fe-2(HPO4)(3)(C2O4)](2): M = 589.8, monoclinic, space group = P2(1) n (no. 14), a = 10.829(1), b = 12.747(1), c = 12.397(1) Angstrom, beta = 95.1(1)degrees, V = 1704.4(3) Angstrom(3), Z = 4, R = 0.036 and R-w = 0.083 [1860 observed reflections with I 2 sigma(I)]. The structure comprises a network of FeO6 octahedra and PO4 tetrahedra forming inorganic layers which are bridged by the oxalate units forming 8-membered channels in which the amine molecule resides. Magnetic susceptibility studies indicate an antiferromagnetic behavior with T-N = approximate to 40 K, the highest known in an open-framework material.
