Synthesis and Crystal Structure of [ Co(L)(NO3)2]·CH3CN
摘要/Abstract
多吡啶配体2,3-二(2-吡啶基)-5,8-二甲氧基喹喔啉(L)与Co(NO3)2·6H2O反应生成配合物[Co(L)(NO3)2]·CH3CN,通过单晶衍射分析确证其结构.配合物的单晶结构中,Co(Ⅱ)离子中心分别与配体L的2个吡啶环中的N原子和2个硝基的4个氧原子形成六配位的八面体配位结构,L以双齿配体形式参与配位.配合物通过π-π芳香体系堆积形成一维链状结构,芳香体系的面面叠加作用可能使配合物的结构更加稳定.
The complex of Co(Ⅱ)with a new polypy ridy l ligand , 2,3-bis (2-pyridyl) 5 , 8-dimethoxyquinoxaline(L), have been sy nthesized and characterized.The crystal structure of title compound has been elucidated by Xray diffraction analyses .In [Co(L)(NO3)2]·CH3CN , the Co(Ⅱ)center is coordinated to the two nitrogen atoms of the two pyridine rings of L which acts as a bidentate ligand .The formation of infinite quasi-one-dimensional chains assisted by the intermolecular face-to-face ary l stacking interactions may have stabilized the crystals of the complex.
