【摘要】 合成了一个水杨醛-1,2-丙二胺 Schiff 碱锰(Ⅲ)单核配合物[Mn(salpn)(CH3OH)(4,4′-bipy)](BPh4).单晶 X-射线衍射结果表明,该配合物属单斜晶系,P2(1)/c 空间群,晶胞参数 a=1.371 7(3)nm,b=2.629 7(5)nm,c=1.358 1(3)nm,d=90 o,β=110.256(4)°,γ=90°.配合物中,中心 Mn(Ⅲ)离子采取畸变的八面体配位构型,4,4′-联吡啶和甲醇分子作为轴向端基配体与 Mn(Ⅲ)离子配位,单核单元之间通过氢键作用构成了一维链状结构.
【Abstract】 A mononuclear Mn(Ⅲ)Schiff base complex[Mn(salpn)(CH3OH)(4,4’-bipy)] (BPh4)has been synthesized.Single crystal X-ray analysis reveals that the complex belongs to monoclinic crystal system,P2(1)/c space group,unit cell dimensions a=1.3717(3),b= 2.629 7(5),c=1.358 1(3)nm,α=90°,β=110.256(4)°,γ=90°.The central Mn(Ⅲ)ion adopts a distorted octahedral geometry.4,4′-bipyridine and methanol act as axial terminal lig- and coordinated with Mn(Ⅲ)ion.The mononuclear units are linked by hydrogen bonds into one dimensional chains.
