  Coordination chemistry of di-2-pyridylamine-based bridging heterocyclic ligands: A structural study of coordination polymers and discrete dinuclear complexes

  摘要：

  Four new bridging ligands containing two di-2-pyridylamine subunits have been synthesised. The coordination chemistry of these, along with one previously reported ligand, has been investigated through reactions with various silver(l), copper(II) and palladium(II) reactants. Typically, reaction of these ligands with silver(l) salts gave 1-D coordination polymers, within which the ligands act as divergent bridging units, while reaction with copper(II) and palladium(II) precursors provided discrete dinuclear complexes with chelating bidentate subunits. The complexes were characterised by a combination of elemental analysis, NMR spectroscopy and X-ray crystallography. The silver coordination polymers displayed interesting variations in supramolecular architecture, attributed to weak secondary interactions, such as Ag center dot center dot center dot pi-bonding.

  Mono- and dinuclear ruthenium(II) complexes of six bridging ligands that contain a central arene (phenyl, naphthalenyl or biphenyl) core to which are attached two di-2-pyridylamine groups have been prepared. These complexes possess six-membered chelate rings. Full assignments of their H-1 NMR spectra are described which provides insight into the comformations of the ligands in these complexes. The extent of metal-metal communication in the dinuclear complexes was probed by electrochemical measurements and related to metal-metal distances. (c) 2007 Elsevier Ltd. All rights reserved.

  The ligand tppda has been designed and synthesized as molecular leverage for helicity control when reacted with Cd2+ ions. The guests MeOH or DMF preferentially stabilize the P-helical isomer, while the guest H2O causes a helix inversion to give the M-helical isomer as the major isomer without any chiral auxiliary.
