Synthesis and study of Fe → Pd interactions in unsymmetric Pd(ii) complexes with phosphinoferrocene guanidine ligands

Abstract

Readily available phosphinoferrocene guanidines coordinate Pd(II) as P,N-chelating or κ³P,N,Fe-bound ligands. As the latter, they give rise to the first donor-asymmetric complexes featuring Fe–Pd dative bonds, which were studied using direct (spectroscopic and electrochemical) methods and theoretical (DFT) approaches.
