A novel organically templated three-dimensional open framework vanadium tellurite: (NH3CH2CH2NH3)2V2Te6O18

A novel organically templated vanadium tellurite (NH3CH2CH2NH3)2V2Te6O18 (1) has been hydrothermally synthesized and characterized by elemental analyses, IR, thermal stability analysis, magnetic susceptibilities and single crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system, space group P21/nP21/n, a=8.891(2)Å, b=8.834(2)Å, c=15.906(4)Å, β=94.789(4)°β=94.789(4)°, V=1181.5(5)Å3, Z=2Z=2, R1[I>2σ(I)]=0.0187R1[I>2σ(I)]=0.0187, wR2[I>2σ(I)]=0.0482wR2[I>2σ(I)]=0.0482. Compound 1 exhibits a novel three-dimensional (3D) vanadium tellurite anion framework composed of vanadium, tellurium, and oxygen atoms through covalent bonds, with the [NH3CH2CH2NH3]2+ cations residing in the channels.

Utilization of ethylenediamine as organic template successfully provides a novel three-dimensional (3D) open framework vanadium tellurite, (NH3CH2CH2NH3)2V2Te6O18, with the [NH3CH2CH2NH3]2+ cations residing in the channels of the inorganic framework.Figure optionsDownload as PowerPoint slide
