摘要：

运用INDO－UHF计算方法研究了CO(Ⅱ) Schiff碱的载氧特性，结果表明，Co(Ⅱ)与O_2的作用是通过σ键组合，并具有较明显的反铁磁性耦合作用, 论证了作为第五轴向配体在可逆载氧过程中的必要性，对比研究了Co－N_2的相互作用. 计算表明，CO(Ⅱ)的Schiff碱络合物可能作为氧氮分离的活性物质，从而具有一定的、潜在的工业应用价值.

Abstract:

The character of Co(Ⅱ) Schiff base complex carrying O_2 was studied by INDO-UHF method. The results showed that the interaction between Co(Ⅱ) and O_2 was completed through σ bond, and the antiferro magnetic coupling was obvious. The ne cessity of fifth axial ligand in the reversible process of O_2 carring was discussed. The interaction between Co(Ⅱ) and N_2 was also studied in comparasion with Co-O_2. The cal culation showed that Co(Ⅱ) Schiff base have potential value for industrial application.
