  ABSTRACT: A new decavanadate, (C4N2H7)4(C6N2H10)V10O28·2H2O, was synthesized by slow evaporation at room temperature and characterized by single crystal X-ray diffraction, IR and UV-Vis spectroscopies. The compound crystallizes in the triclinic system, P-1 space group with the cell parameters: a = 11.200(5) Å, b = 12.056(9) Å, c =20.511(7) Å, α = 73.40(4), β = 84.67(3), γ = 63.51(5), Z = 2 and volume V = 2373.7(1) Å3. The formula unit is composed of one decavanadate [V10O28]6- anion, four 2-methylimidazolium (C4N2H7)+ cations, one 2-amino-4-picolinium (C6N2H10)2+ cation and two water molecules. In the crystal, the layers of decavanadate groups, organic cations and water molecules stack up parallel to the (011) plane. The cohesion is provided by N-H···O, O-H···O hydrogen bonds and Van der Waals interactions leads to a three-dimensional structure. The absorbance spectrum measurement shows an optical band gap of 3.27 eV which allows us to conclude that this compound is a semiconductor material.
