【 摘 要 】

The complex of Tetrakis(2-amino-3-methylpyridine)copper(II) sulfate tetrahydrate has been synthesized in a ratio of 1: 6 metal to ligand in methanol. The percentage of copper in the complex measured by Atomic Absorption Spectrometer (AAS) showed the complex formula was Cu(2-amino-3-metilpyridine)4SO4(H2O)n(n = 3, 4, or 5). The analysis of TG/DTA showed that 1 mole of complex contains 4 moles of H2O. The conductivity measurement indicated that the complex is in 1 to 1 electrolyte. The formula of the complex was estimated as [Cu(2-amino-3-metilpyridine)4]SO4•4H2O. The complex was paramagnetic with μeffof 1.85 BM. The UV-Vis spectra showed a band peak at 730 nm with an electronic transition Eg→T2g. IR spectral data indicated that the functional groups of N-pyridine 2-amino-3-metilpyridine coordinated to ion Cu(II). The geometry of the complex was probably square planar.
