Cover Feature: A Phosphine Functionalized β‐Diketimine Ligand for the Synthesis of Manifold Metal Complexes (Chem. Eur. J. 58/2020)

Abstract

A bis(diphenyl)-phosphine functionalized β-diketimine ligand is depicted in the cover image. This ligand coordinates in a very flexible manner to a number of transition metal ions. The newly designed ligand features a symmetrically placed PNNP-type pocket. Due to the hard and soft donor atoms (N vs. P) the ligand can stabilize various coordination polyhedra. A complete series ranging from coordination numbers 2 to 6 was realized, resulting in linear, trigonal planar, square planar, tetrahedral, square pyramidal, and octahedral coordination polyhedral. More information can be found in the Full Paper by P. W. Roesky et al. on page 13191.
