Structural and magnetochemical investigations into spin-spin exchange couplings in homo- and heteronuclear d-f complexes

在该项目的准备部分，有机金属Eu(II)和Gd(III)物种将与反应性有机金属过渡金属分子结合。前者由二环戊二烯和三环戊二烯组成，后者由顺磁性过渡金属环戊二烯基卤化物组成。这些研究是关于稀土元素--卤素--过渡金属的交换途径的。在该项目的理论部分，将把同核过渡金属和稀土化合物磁化学分析的计算机程序扩展到所研究的异核体系。

In the preparative part of the project organometallic europium(II) andgadolinium(III) species will be combined with reactive organometallictransition metal molecules. The former systems comprise di- andtricyclopentadienides, whereas the latter systems consist ofparamagnetic transition metal cyclopentadienyl halides. Theinvestigations are of interest with respect to the exchange pathwaylanthanide--halogen--transition metal. In the theoretical part of the project the computer program formagnetochemical analysis of homodinuclear transition metal andlanthanide compounds will be extended with regard to the heteronuclearsystems under investigation.
