Article Description

The tridentate ligand 2,6-diallylpyridine (DAP) has been used to synthesize novel complexes of iridium(I), ruthenium(II), palladium(II) and platinum(II) of formulae [Ir(COD)(DAP)][IrCl 2 (COD)], [IrCl(CO)(DAP)], [Ir(COD)(DAP)]ClO 4, [RuCl 2 (PPh 3 )(DAP)],[PdCl 2 (DAP) 2 ],[PtCl 2 (DAP)]. All the complexes have been characterized by elemental analysis, IR, and 1 H NMR spectroscopy. The molecular structures of [RuCl 2 (PPh 3 )(DAP)] and [PdCl 2 (DAP) 2 ] have been determined by single-crystal X-ray diffraction studies. Crystals of the ruthenium complex are orthorhombic, space group Pbca, with Z = 8 in a unit cell of dimensions a 11.492(5), b 18.942(3), c 23.083(9) Å. Crystals of the palladium complex are triclinic, space group P 1 with Z = 1 in a unit cell of dimensions a 7.950(4), b 8.745(4), c 9.578(4) Å, α 113.02(3), β 90.75(3), γ 116.65(3)°. Both structures were solved by Patterson and Fourier methods and refined by blocked full-matrix least-squares to R = 0.0528 for 2742 observed reflections in the first complex and by full-matrix least-squares to R = 0.0252 for 1948 observed reflections in the second. In the octahedral ruthenium complex, DAP acts as a tridentate ligand adopting a mer configuration and the phosphine ligand is trans to the pyridinic nitrogen, while in the trans square-planar palladium complex DAP acts as a monodentate N -donor ligand.
