Abstract

Synthesis strategy of hybrids Polyoxometalates have drawn a lot of attention owing to interesting. Herein, we describe, the one pot process used to synthesize a new hybrid polyoxotungstate, (C₆H₂₀N₃)₂[TeW₆O₂₄].8H₂O, at a temperature of 200°C. This preparation was carried out by mixing equimolar amounts of H₂WO₄, C₆H₁₇N₃, and H₆TeO₆. The compound was characterized by infrared and UV-visible spectroscopy techniques, as well as by X-ray diffraction. The compound crystallizes in the monoclinic system with the space group P2₁/c. The unit cell are: a = 8.74874(14) Å, b = 12.5894(2) Å, c = 18.5176(3) Å, α = 90°, β = 92.6078(14)°, γ = 90°. The compound consists of a non-protonated Anderson-type heteropolyanion [TeW₆O₂₄]^6- stabilized by two organoammonium cations [C₆H₂₀N₃]³⁺ and eight water molecules. The polyoxoanion [TeW₆O₂₄]^6- adopts an Anderson-Evans type structure of class A. Thus, the polyanion is bult of six {WO₆} units surrounding a {TeO₆} octahedron. The six {WO₆} are linked together by edges sharing and connected around the heteroatom, via oxygen atoms, forming a planar structure with approximate D3d symmetry. The cohesion of the three-dimensional structure is ensured by hydrogen bonds between the polyanions, the organoammonium groups, and the water molecules, thereby providing significant stability to the compound. UV–Visible absorption spectroscopy shows a strong absorption band at 296nm attributed to Ligand-Metal Charge Transfer (LMCT) transition of the O→W and the main IR absorption bands of the polyanion appear at: 942 cm⁻¹, 875 cm⁻¹, 766 cm⁻¹ and 599 cm-¹.

AB  - Synthesis strategy of hybrids Polyoxometalates have drawn a lot of attention owing to interesting. Herein, we describe, the one pot process used to synthesize a new hybrid polyoxotungstate, (C6H20N3)2[TeW6O24].8H2O, at a temperature of 200°C. This preparation was carried out by mixing equimolar amounts of H2WO4, C6H17N3, and H6TeO6. The compound was characterized by infrared and UV-visible spectroscopy techniques, as well as by X-ray diffraction. The compound crystallizes in the monoclinic system with the space group P21/c. The unit cell are: a = 8.74874(14) Å, b = 12.5894(2) Å, c = 18.5176(3) Å, α = 90°, β = 92.6078(14)°, γ = 90°. The compound consists of a non-protonated Anderson-type heteropolyanion [TeW6O24]6- stabilized by two organoammonium cations [C6H20N3]3+ and eight water molecules. The polyoxoanion [TeW6O24]6- adopts an Anderson-Evans type structure of class A. Thus, the polyanion is bult of six {WO6} units surrounding a {TeO6} octahedron. The six {WO6} are linked together by edges sharing and connected around the heteroatom, via oxygen atoms, forming a planar structure with approximate D3d symmetry. The cohesion of the three-dimensional structure is ensured by hydrogen bonds between the polyanions, the organoammonium groups, and the water molecules, thereby providing significant stability to the compound. UV–Visible absorption spectroscopy shows a strong absorption band at 296nm attributed to Ligand-Metal Charge Transfer (LMCT) transition of the O→W and the main IR absorption bands of the polyanion appear at: 942 cm⁻¹, 875 cm⁻¹, 766 cm⁻¹ and 599 cm-¹.
