摘要： 描述了两个具有管状氢键假想孔道结构的化合物[Ni(en)3][GeF6][JLG-1(Ni)]和[Co(en)3].[GeF6][JLG-1(Co)].在这两个结构中,[GeF6]2-阴离子与手性金属配合物阳离子[M(en)3]2+(M=Ni,Co)通过F…N之间复杂的弱氢键相互作用,在沿着63螺旋轴方向形成六方蜂窝状排布的管状氢键假想孔道.结构研究发现,配对的[GeF6]2阴离子和手性[M(en)3]2+阳离子同属于D3点群,这是JLG-1(Ni)和JLG-1(Co)形成管状氢键假想孔道的关键.这一研究成果对设计合成氢键假想孔道体系具有一定的指导意义.

Abstract: Two interesting H-bonded pseudo-channel structures [Ni(en)3][GeF6][JLG-1(Ni)] and [Co(en)3][GeF6][JLG-1(Co)] were describes in this work.The [GeF6]2-anions interact with the chiral complex cations [M(en)3]2+(M=Ni,Co) in such a way that pseudo-channels were formed along the 63 screw axis in a hexagonal,honeycomb array are created based on weak H-bonding of F…N atoms.It is believed that the chiral([M(en)3]2+) cations paired with [GeF6]2- anions in a D3 point symmetry is responsible for the fascinating arrangement in JLG-1(Ni) and JLG-1(Co).This work will be useful for the design of H-bonded pseudo-channel system.
