Abstract New aryl-Pt(II) complex, including 2,2′-dipyridylamine (dpya) as a bidentate ligand was obtained through the reaction of [(p-tolyl)2Pt(Me2S)2] with 2,2′-dipyridylamine in a 1:1 stoichiometry. The aryl-Pt(IV) complex was synthesized during the oxidative addition reaction of [Pt(p-tolyl)2dpya] with MeI. In these organoplatinum complexes, dpya was bonded to the Pt center via N2 atoms. The MeI was used as a reagent for investigation of oxidative addition reaction (ox. add) on the Pt(II) center, which led to the formation of Pt(IV) complex with octahedral geometry. It was shown that the synthesized Pt(II) and Pt(IV) complexes contain a 1:1 M:L molar ratio. Moreover, conductivity measurements confirmed the non-electrolyte nature of the platinum complexes. These organoplatinum complexes have been characterized by X-ray crystal structure, 1H NMR, FT-IR, conductometry, elemental analysis and UV/Vis spectroscopy. Single X-ray crystal structure showed the asymmetric unit of the Pt(II) complex included one Pt(II) atom, one 2,2′-dipyridylamine and two p-tolyl groups. Furthermore, oxidative addition reaction of iodomethane with Pt(II) complex at 29, 32, 35 and 38 °C was studied and the enthalpy and entropy of activation, activation energy (Ea) and rate constants were calculated.

含2,2'-二吡啶胺的新型芳基铂配合物的合成；单晶结构、电化学研究和动力学参数计算

摘要 通过 [(p-tolyl)2Pt(Me2S)2] 与 2,2'-二吡啶胺反应获得了新的芳基-Pt(II) 配合物，包括 2,2'-二吡啶胺 (dpya) 作为双齿配体。 1:1 的化学计量比。在[Pt(p-tolyl)2dpya]与MeI的氧化加成反应过程中合成了芳基-Pt(IV)配合物。在这些有机铂配合物中，dpya 通过 N2 原子与 Pt 中心键合。MeI 被用作研究 Pt(II) 中心的氧化加成反应 (ox. add) 的试剂，这导致形成具有八面体几何形状的 Pt(IV) 络合物。结果表明，合成的 Pt(II) 和 Pt(IV) 配合物含有 1:1 M:L 的摩尔比。此外，电导率测量证实了铂络合物的非电解质性质。这些有机铂配合物已通过 X 射线晶体结构、1H NMR、FT-IR、电导测定、元素分析和紫外/可见光谱。单个X射线晶体结构显示Pt(II)配合物的不对称单元包括一个Pt(II)原子、一个2,2'-二吡啶胺和两个对甲苯基。此外，研究了碘甲烷与 Pt(II) 配合物在 29、32、35 和 38 °C 下的氧化加成反应，并计算了活化焓和熵、活化能 (Ea) 和速率常数。
