| 摘 要： | A new Co(Ⅱ) complex of 14o-membored hexaaza macrocyclic ligand with two Cl~- in axial positions Co(C_(18)H_(18)N_6)Cl_2]·2H_2O, has been synthesized by the template condensation of 2,6-diacetylpyridine with hydrazine in the presence of cobalt chloride. Elemental analysis, electronic spectra, electroconductance and magnetic susceptibility, etc. measurements indicate this complex to be a sixcoordinate distorted octahedron. The observed magnetic moments (4.16 BM) are lower than the expected value (5.2 BM). The deviation and correlation of The axial ligand field strength with Co(Ⅱ) spin state are discussed. The values of Dq, B, β and the band positions have been evaluated from the electronic spectral data by the ligand field method. It has been proved that the calculated values are in fairly good agreement with the experimental ones.
