A novel decavanadate salt Mg(H2O)6(C6H14N2)2V10O28·8H2O is obtained by the reaction of vanadium oxide and 1,4-diazabicyclo [2.2.2] octane (DABCO). The title compound is characterized by infrared (IR) spectroscopy and powder X-ray diffraction (XRD). The spectroscopic characterization confirms the presence of the different groups in the structure. Powder XRD confirms the purity of the phase. Optical properties are recorded at room temperature using UV-Visible spectroscopy in the spectral range of 250-800 nm. According to the single crystal XRD analysis, the structure of the compound is orthorhombic: a = 17.927(6) Å, b = 15.798(6) Å, c = 15.723(5) Å, V = 4452.8(7) Å3, and Z = 4. The formula unit of Mg(H2O)6(C6H14N2)2V10O288H2O is formed by a decavanadate group, the polyhedron, two organic (C6H14N2)2+ cations, and eight water molecules. In the crystal, molecules are linked by O–H...O and N–H...O hydrogen bonds, forming a three-dimensional network. [ABSTRACT FROM AUTHOR] |
