摘要: 化学模拟生物固氮仍然是当代化学学科的重大基础课题之一,其中心也仍然是探索过渡金属对氮分子的络合活化规律。本文试图用自己建立的以HMO为主,并揉合EHMO、CNDO的量子化学方法研究过渡金属对氮分子的活化问题。1计算方法和结果对氮分子络合活化的计算方法与乙烯分子相似。

关键词: 络合催化, 固氮活性, 量子化学计算

Abstract: The catalytic activities of transition metals for the activation of N2were studies by quantum chemical method, combining HMO with EHMO and CNDO. The results obtained are in agreement with experimetal data, and indicate that side-on coordination of N2on transition metals is better than that of end-on and was proved by experimental facts indirectly.
