  Complexes of 2,5-Bis(α-pyridyl)pyrrolate with Pd(II) and Pt(II): A Monoanionic Iso-π-Electron Ligand Analog of Terpyridine

  摘要：

  Palladium and platinum metal complexes of 2,5-bis(alpha-pyridyl)-pyrrolate (PDP) are reported and characterized by spectroscopic methods, single-crystal X-ray diffraction, and elemental analysis. The single-crystal X-ray structures of these complexes exhibit structural features indicative of significant pi-backbonding. To illustrate the effect, bond lengths are statistically compared to unmetalated PDP and to a previously reported Zn(II) complex that exhibits no backbonding. Density functional theory calculations are used to aid understanding of the electronic structural basis of the observed phenomena.

  New dipyridylpyrrole N-oxide ligands HL1 and HL2 are designed and synthesized via oxidation of 2-(5-(pyridin-2-yl)-1H-pyrrol-2-yl)pyridine (Hdpp) by using 3-chloroperbenzoic acid (m-CPBA) in CH2Cl2. The treatment of ZnEt2 with two equiv. of HL1 and HL2 affords [Zn(L1)2] and [Zn(L2)2] in medium yield, respectively. These ligands and zinc complexes are fully characterized by NMR, IR, UV-vis and ESI-MS

  A series of platinum(II) complexes with the 2,5-bis(α-pyridyl)pyrrolate (PDP) ligand were synthesized. The ligand (X) trans to the central pyrrole nitrogen of PDP was found to play a key role in whether tridentate monomeric or bidentate clamshell dimer complexes were formed. When X = CH3 or C6H5, strong σ-donor ligands, only dimeric clamshell structures were observed. In contrast, when X = Cl or I
