Two palladium(II) complexes, [Pd(phen)(N identical withCCH(3))(2)]O(3)SCF(3) (1) and Pd(phen)(mu-OH)O(3)SCF(3).2H(2)O (2) (where phen= 1,10-phenanthroline), have been crystallized following the reaction of Pd(phen)Cl(2) with silver triflate, Ag(O(3)SCF(3)), in acetonitrile and water, respectively. The structures of both complexes are based on a Pd(phen)(2+) metal core, with two acetonitrile molecules binding in a monodentate fashion in complex 1 and two hydroxo bridges holding together two cores to form a dimer in complex 2. Additionally, both complexes present a hydrogen bonded 3-D network involving the triflate anions in 1, and water and triflate anions in 2. Both complexes have been characterized by infrared and (1)H NMR spectroscopy and their crystal structures determined by X-ray crystallography.
两种钯(II)配合物,[Pd(phen)(N≡CCH₃)₂][O₃SCF₃]₂(1)和[Pd(phen)(μ-OH)]₂[O₃SCF₃]₂·2H₂O(2)(其中phen = 1,10-菲咯啉),分别是在乙腈和水中,Pd(phen)Cl₂与三氟甲磺酸银Ag(O₃SCF₃)反应后结晶得到的。两种配合物的结构均基于Pd(phen)²⁺金属核,在配合物1中两个乙腈分子以单齿方式配位,在配合物2中两个羟基桥将两个核连接在一起形成二聚体。此外,两种配合物都呈现出氢键三维网络,在1中涉及三氟甲磺酸根阴离子,在2中涉及水和三氟甲磺酸根阴离子。两种配合物均通过红外光谱和¹H NMR光谱进行了表征,并通过X射线晶体学确定了它们的晶体结构。
