摘要：

The reaction between the electron-rich iridium(I) complex, [Ir(COD)(PMe3)(3)]Cl, and the amino acid, 2-aminopent-4-enoic acid leads to the direct formation of a product with facial geometry about the iridium center with three PMe3 groups, and tripodal coordination of the amino acid via N, O and C. The synthesis of this product can be visualized as involving the formation of an iridium hydride followed by insertion of the pendant alkene. Two different crystal structures of the product were determined, one containing a chloride counterion and one with a tetraphenylborate counterion. The change in counterion leads to very different intermolecular interactions. (C) 2014 Elsevier B.V. All rights reserved.
