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 VOsN 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. |
