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.
