摘要：

Models get choosey: Structurally characterized mono- and dicationic yttrium methyl complexes (3 and 4) are accessible by protonolysis of the hexamethylate complexes (1 and 2) and function as models for the homogeneous catalysts for 1,4-cis-selective polymerization of 1,3-dienes by the industrially applied multicomponent catalyst.
