Abstract

A series of platinum(II) complexes supported by the tridentate bis(phosphine) phosphido ligand bis(2-diisopropylphosphinophenyl) phosphide) [Pr-i-PPP] have been synthesized and characterized (1-4). X-Ray structural studies of [Pr-i-PPP] PtCl (1) and [ Pr-i-PPP] PtCH3 (3) complexes show meridional [Pr-i-PPP] ligands around approximately square-planar platinum centers. Structural data and NMR analysis highlight a strong trans influence for the phosphido phosphorous donor, comparable to that of the anionic aryl carbon of the classic PCP pincer complexes. A series of thermally stable [PPP] Pt(IV) compounds, including [ PPP] Pt(CH3)(2)X [X = I (5) and SbF6 (6)], were also synthesized. The study of the binding affinity of SO2 and NO to complex 1 has also been addressed.
