摘要:

有机物中芳香性的研究已经相当广泛而深刻,随着对芳香性概念认识的不断广泛化,在无机化合物领域中对金属簇合物的芳香性研究日益增多,但是将芳香性概念用于过渡金属团簇的研究较少。多金属团簇具有丰富的配位化学性质和广阔的应用前景,促进了多金属团簇的制备研究。研究结果表明:过渡金属团簇相较于有机物及非金属无机团簇来说,由于d轨道的参与成键,成键方式比其他两者复杂。计算发现过渡金属团簇的芳香性远远大于有机物和非金属无机团簇的芳香性,这是因为有机物和非金属无机团簇的芳香性主要来自于s轨道和p轨道的成键贡献,也就是σ芳香性和π芳香性的贡献,而过渡金属团簇还有d轨道参与反应,因此团簇芳香性的成分更加复杂,不但有σ芳香性和π芳香性,更有很大成分是δ芳香性。在同一过渡金属团簇中,能量低且结构稳定的团簇都比其能量高的异构体具有较高的芳香性或较低的反芳香性,这也为我们把芳香性用于过渡金属团簇稳定性的探讨提供了有利的参考依据。一般情况下,同一团簇多重度为1芳香性最高,这可能是多重度增加后,电子自旋度增大,团簇中的排斥力增大,导致结构不稳定,从而使团簇的芳香性降低,但随着多重度的增大,磁性大小和团簇的芳香性似乎没有呈现明显规律。
