双核VIV配合物的合成、晶体结构及磁性研究
Synthesis,Crystal Structure and Magnetic of Di-Nuclear VIV Complex
摘要
Abstract
A reduced di-nuclear VIV complex with the chemical formula[VIV2O3(L)(Me-Im)4](1)was synthesized under solvothermal conditions,employing vanadium pentoxide(V2O5)as vanadium source,pyrazole-3,5-dicarboxylic acid(H2L)and N-methylimidazole(Me-Im)as ligands.Complex 1 was fully characterized by single-crystal X-ray diffraction,powder X-ray diffraction,Fourier transform infrared spectroscopy,thermogravimetric analysis and X-ray photoelectron spectroscopy.The single-crystal X-ray diffraction results indicate that complex 1 crystallizes in the monoclinic system,with the space group P21/c.The structure contains two crystallographically independent VIV ions,which are connected by the completely deprotonated pyrazole-3,5-dicarboxylic acid(L2-)as a bridging ligand.Additionally,four Me-Im act as capping ligands,coordinating with these two VIV ions,collectively constructing the zero-dimensional di-nuclear VIV structure of complex 1.Furthermore,the magnetic properties of complex 1 were investigated due to the presence of single electrons in the VIV d-orbital,and the results reveal the presence of ferromagnetic interactions in the compound.关键词
