experiments. The molecular structures of [Cp*Ir(L2)Cl][BPh4] (6) (Cp*-pentamethylcyclopentadienyl) and trans-[PdCl2(L3)PEt3] (8) have been established by means of X-ray crystallography. The crystal structure of 6 consists of piano stool geometry with respect to the Ir(III) center with N,N-bidentate coordinated ligands. The six-membered chelate ring formed by Ir(1), N(1), C(5), C(6), O(1), N(2) possesses
摘要Pd(II),Pt(II),Zn(II)和Ir(III)与5-吡啶取代的N-甲基异恶唑烷(4-(2-甲基-3-苯基异恶唑烷-5-基)-吡啶(L1 ),2-(2-甲基-3-苯基异恶唑烷-5-基)-吡啶(L2),2-(2-甲基-3-二茂铁基异恶唑烷-5-基)-吡啶(L3))的制备及特征在于1 H,13 C和31 P NMR。配位的异恶唑烷的构型已通过NMR偶合常数分析和通过2D-ROESY实验进行的核Overhauser测量确定。[Cp * Ir(L2)Cl] [BPh4](6)(Cp *-五甲基环戊二烯基)和反式-[PdCl2(L3)PEt3](8)的分子结构已通过X射线晶体学确定。6的晶体结构由相对于Ir(III)中心具有N,N-双齿配位体的钢琴凳几何结构组成。由Ir(1),N(1),C(5),C(6),O(1),N(2)形成的六元螯合环具有“扭转桶”构象。8的晶体结构由中性方形平面Pd(II)配合物组成。L
