Intermolecular interactions and electronic properties in phosphino-(oligothiophene) palladium(II) and platinum(II) complexes
Stott, Tracey L.,Wolf, Michael O.,Patrick, Brian O.
, p. 383 - 391 (2008/03/14)
A series of Pt(II) and Pd(II) complexes containing diphenylphosphino- substituted oligothiophene ligands ranging from 1 to 3 thiophene rings in length have been prepared. Crystal structures of four of these complexes were determined via single X-ray crystal diffraction and the solid-state packing arrangements found to vary with both the metal and the thiophene-containing ligand. In some cases, π-stacking between thiophene rings are found for the oligothiophene ligands. Solution and solid-state absorption spectra of these complexes are reported.

Tertiary phosphines containing 2-thienyl group of the type PRnth3-n (R = Me, Et or Ph; th = 2-thienyl; n = 1 or 2) have been prepared and their coordination chemistry has been studied. Series of complexes of the types [PdCl2(PRnth3-n)2]. [PtX2(PRnth3-n)2] (X = Cl, I, Me), [PtXY(PRnth3-n)2] (X = Cl; Y = Me or SnCl3), [PtMe(py)(PRnth3-n)2][PF6], [MCl(μ-Cl)(PR2th)]2 (M = Pd or Pt), [PtCl2(CO)(PR2th)], [RhCl3(PEt2th)3] and [RhCl(CO)(PRnth3-n)2] have been synthesized with these phosphines and characterized by elemental analyses, IR, 1H, 31P, 119Sn, 195Pt NMR spectroscopy. In all the cases phosphine acts as a monodentate ligand with only phosphorus-metal coordination.
The Chemistry of Heteroarylphosphorus Compounds. Part 15. Phosphorus-31 Nuclear Magnetic Resonance Studies of the Donor Properties of Heteroarylphosphines towards Selenium and Platinum(II)
Allen, David W.,Taylor, Brian F.
, p. 51 - 54 (2007/10/02)
The donor properties of a series of heteroarylphosphines (bearing 2- and 3-furyl, 2- and 3-thienyl, and 1-methylpyrrol-2-yl groups directly bound to phosphorus) towards selenium and platinum(II) acceptors have been investigated by 31P n.m.r. studies of the one-bond coupling constants 1J(77Se-31P) and 1J(195Pt-31P).It is shown that the respective coupling constants increase as the heteroaryl groups become more electron withdrawing, indicating an increased s character for the phosphorus lone pair.The implications of this for the relative donor properties of the heteroarylphosphines and PPh3 are considered.
