N2 - The reactions of [(LiPrNi)2(μ-η2:η2-S4)] (I) and [(LiPrNi)2(μ-η2:η2-Se2)] (II) (LiPr = CH[C(Me)N(2,6-iPr2C6H3)]2) with decamethylsamarocene [Sm(Cp*)2(Тhf)2] (Cp* = η5-C5Me5) are studied. It is assumed that the reactions afford hetero-d/f-metal complexes. However, these complexes are not observed but the transfer of chalcogens from Ni to Sm and the formation of [(Sm(Cp*)2(Тhf))2(μ-S)] (III) and [(Sm(Cp*)2(Тhf))2(μ-Se)] (IV) occur. The second reaction products are [(LiPrNi)2(μ-η2:η2-S2)] (V) in the case of sulfur and [(LiPrNiI)2(μ-η6:η6-C7H8)2] (VI) in the case of selenium. All reaction products have been described previously, but compounds III and V are isolated as new crystalline phase, the structures of which are determined by X-ray diffraction analysis (CIF files CCDC nos. 1559045 (V) and 1559046 (III)).
