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.
