Metal Complexes of Biologically Important Ligands, CVII [1], Formation of Tris(pentamethylcyclopentadienyl-μ-L-prolinato-iridium) Tris(trifluoromethanesulfonate) with Chiral Self Recognition

  • Karlheinz Sünkel , Winfried Hoffmüller and Wolfgang Beck

The structure of the title complex consists of [Ir3(C5Me5)3(L-prolinate)3]3+ complex cations and CF3SO3- anions. Each iridium atom is coordinated in a distorted tetrahedral manner by one cyclopentadienyl group, two carboxylate O atoms and the prolinate N atom. The iridium atoms are bridged by the carboxylate groups. Each of the three stereogenic iridium atoms has the same (S) configuration, i. e. the trimerization of the [Ir(C5Me5)(L-prolinate)]+ fragment occurs with chiral self recognition.
