Synthesis and Properties Study of 4-Methylaminopyridine-iron Isothiocyano Complex Crystalline Materials
A novel organic-inorganic hybrid[Fe(NCS)6][C6N2H9]3(1)crystalline material was synthesized by slow evaporation method using FeCl3·6H2O,4-methylaminopyridine and NH4SCN as raw materials,methanol and water as mixed solvents.The structure and properties of compound 1 were determined by infrared(IR),dielectric,X-ray single crystal diffraction,thermal stability(TG)and other tests.The X-ray single crystal diffraction test results show that the space group of compound 1 is P-1,which is belongs to triclinic system.A relatively stable three-dimensional network structure is presented in the crystal through hydrogen bonding and π-π stacking interaction.The dielectric constant of the material presents a reversible dielectric anomaly during the process of cooling and heating,suggesting that compound 1 was a reversible dielectric anomaly functional material.
