Utilizing the pyridinediimine ligand [(2,6-(i)PrC(6)H(3))N═CMe)(N((i)Pr)(2)C(2)H(4))N═CMe)C(5)H(3)N] (didpa), the iron(II) complexes Fe(didpa)Br(2) (1), [Fe(Hdidpa)Br(2)][PF(6)] (2), and [Fe(Hdidpa)CH(3)CN(OH)][2PF(6)] (3) were synthesized and characterized by X-ray diffraction and spectroscopic methods. The X-ray data show that the didpa scaffold is capable of forming intramolecular hydrogen bonds in the solid state located within the secondary coordination sphere of complexes 2 and 3. These hydrogen bonds are responsible for stabilizing the iron(II) hydroxo ligand in 3, which originates from H(2)O.
利用吡啶二亚胺配体[(2,6-(i)PrC(6)H(3))N═CMe)(N((i)Pr)(2)C(2)H(4))N═CMe)C(5)H(3)N](didpa),合成并通过 X 射线衍射和光谱方法表征了铁(II)配合物 Fe(didpa)Br(2)(1),[Fe(Hdidpa)Br(2)][PF(6)](2)和[Fe(Hdidpa)CH(3)CN(OH)][2PF(6)](3)。X 射线数据表明,在配合物 2 和 3 的次级配位球中,didpa 支架能够在固态中形成分子内氢键。这些氢键负责稳定 3 中源自 H(2)O 的铁(II)羟基金属配体。
