摘      要：The double crown hexakis[(di-μ-benzylthio)nickel]cluster,[Ni_(6)(SCH_(2)C_(6)H_(5))_(12)]·C_(2)H_(5)OH,was obtained by reacting C_(6)H_(5)CH_(2)SNa with[(CH_(3))_(2)CHOCS_(2)]_(2)Ni in EtOH.The results of electrochemical studies show that[Ni_(6)(SCH_(2)C_(6)H_(5))_(12)]is a quasi-reversible process.The crystal structure of[Ni_(6)(SCH_(2)C_(6)H_(5))_(12)]·C_(2)H_(5)OH is composed of discrete[Ni_(6)(SCH_(2)C_(6)H_(5))_(12)]and C_(2)H_(5)OH solvent molecules.Each Ni atom is surrounded by four S atoms of theµ2-SCH_(2)C_(6)H_(5)ligands in a distorted square-planar structure.The C_(6)H_(5)CH_(2)S-side chains are arranged in the axial and equatorial positions,alternately,concerning the pseudo-hexagonal axis of the molecule.Strongπ-πand C-H···πeffects form the supramolecular nano-channel along the a-axis in the crystal,which wraps the solvent ethanol molecules in it.In addition,a wall is formed along the b-and c-axes,so that the ethanol molecules can freely enter and leave along the a-axis.These effects result in the ability of the title compound to adsorb and desorb ethanol molecules.Thermogravimetric analysis and powder X-ray diffraction at different temperature are provided to demonstrate this point.
