A Dimeric eta(1),eta(5)-Germole Dianion Bridged Titanium(III) Complex with a Multicenter Ti-Ge-Ge-Ti Bond

摘要

Dimeric germole dianion bridged Ti-III and Zr-IV complexes have been synthesized. In these complexes, the germole dianion adopts a formal eta(1),eta(5) coordination to the two metal centers. The bonding situation in these bridged dimers is dominated by a covalent Ge-Ge interaction that results, for example, in a strong antiferromagnetic coupling of the d(1) Ti centers.
