Synthesis and coordinative properties of a hybrid bis(diphenylphosphino)methane–terpyridine
Abstract
A newly-synthesized 4′-[bis(diphenylphosphino)methane]–2,2′∶6′,2 ″-terpyridine-based (dppm–terpy) ligand forms complexes by selective complexation of the terpy or diphos segment, respectively, with Fe(II) or Pd(II) salts; in the latter case, an X-ray structural analysis reveals the formation of a neutral square-planar complex assembled from the deprotonated ligands.
