Abstract: An inorganic-organic hybrid compound, [H3NC2H4NH2]VOPO4 was synthesized by meansof the hydrothermal method.It was crystallized in a monoclinic system, a space group P21/c,with the crystal cell parameters: a=0.922 85(11) nm, b=0.729 94(9) nm, c=0.984 95(11)nm, β=101.280(3)°, V=0.650 67(13) nm3, Mr=223.02 g/mol, Dc=2.277 g/cm3, Z=4,R= 0.031 5, ωR= 0.086 5, GOF = 1.085.The VO5N octahedra chains are corner-linked byPO4 tetrahedra; the VO5N octahedra are all trans-linked with V-O bonds being alternately short and long.The monoprotonated ethylenediamine was intercalated between the layers with one end coordinating to V and the other end as an H-bond donor interacting with a terminal O atom of PO4 from a neighboring sheet.The elementary analysis, infrared spectrum characters and thermal stability were also given.
