(Hdea)2[(H2C4O4)VO2F]·H2O (dea: diethylamine) crystallizes in the monoclinic system, space group C2/c. The structure can be described as a succession of equivalent layers perpendicular to b. The anionic [(H2C4O4)VO2F] n 2n− polymeric chain is composed of trigonal bipyramidal VO4F polyhedra and fumaric acid (H2C4O4) groups sharing O2 corners. The cohesion of the structure is provided by a network hydrogen-bonding. The IR and Raman spectra exhibit characteristic bands of all groups present in the structure. Additionally UV-Vis diffuse reflectance spectrum was recorded in order to investigate the band gap nature. The measurements show that this compound exhibit semiconducting behavior with an optical band gap of 3.51eV.
