WebFeb 26, 2024 · The electronic features of the selected coordination ligands span from the significant σ-donor ability of 4-OHp to the highly π-accepting bpz. The intermediate σ-donating properties of the other chelating ligands decrease in the sequence bpy > phen > dip > 4-Clp, while their π-accepting character increases from bpy to 4-Clp.
WebJul 12, 2004 · Stable, chloride-induced monohapto-bonding mode for an allyl ligand in a Pd (II) complex bearing a new bidentate phosphonite-oxazoline ligand Stable, chloride-induced monohapto-bonding mode for an allyl ligand in a Pd (II) complex bearing a new bidentate phosphonite-oxazoline ligand Inorg Chem. 2004 Jul 12;43 (14):4172-7. doi: … WebA short and concise overview is given on the scarce literature on phosphonite related chemistry. Structural differences in the complexes obtained due to steric influences of the ligands are discussed. Ligand 1, bearing 2-tert-butylphenolate groups, led to orthometallated complexes cis-[MCl{1-κ 3 C,P,P}] (M = Pd, Pt) and to trans- [RhCl(CO) (1)].
