A series of platinum(II) complexes supported by the tridentate bis(phosphine)phosphido ligand bis(2-diisopropylphosphinophenyl)phosphide) [(i)Pr-PPP] have been synthesized and characterized (1-4). X-Ray structural studies of [(i)Pr-PPP]PtCl (1) and [(i)Pr-PPP]PtCH(3) (3) complexes show meridional [(i)Pr-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(CH(3))(2)X [X = I (5) and SbF(6) (6)], were also synthesized. The study of the binding affinity of SO(2) and NO to complex 1 has also been addressed.
一系列由三齿双(膦)磷配位基双(2-二异丙基膦基)苯膦([(i)Pr-PPP])支撑的铂(II)配合物已被合成并进行了表征(1-4)。[(i)Pr-PPP]PtCl(1)和[(i)Pr-PPP]PtCH(3)(3)配合物的 X 射线结构研究表明,约为四方平面铂中心周围的[(i)Pr-PPP]配体呈轴向。结构数据和 NMR 分析强调了磷原子供体的强反式影响,类似于经典 PCP 钳式配合物中阴离子芳基碳的影响。一系列热稳定的[PPP]Pt(IV)化合物,包括[PPP]Pt(CH(3))(2)X [X = I(5)和 SbF(6)(6)],也被合成了。还研究了 SO(2)和 NO 与 1 号配合物的结合亲和力。
