摘要
以1,10-邻菲啰啉(phen)和叠氮化钠(NaN3)为配体,在水热条件下成了一个新颖的双核配合物[Co2(μ1,1-N3)2(phen)2(N3)2](1),并通过元素分析、红外光谱、热重分析和X-射线单晶衍射对其结构进行了表征.该配合物属于三斜晶系,P-1空间群.叠氮离子通过EO桥联模式将两个相同的Co(phen)(N3)2单元连接在一起,形成了双核结构单元.磁性研究表明:配合物1呈现亚铁磁行为.
A novel dinuclear Co(Ⅱ) complex, [ Co2 ( μ1,1 - N3 )2 ( phen)2 ( N3 )2 ] ( 1 ) based on 1,10 - phenanthroline (phen) and NaN3 has been hydrothermally synthesized and characterized by elemental analysis, infrared spectrum (IR), thermogravimetric analysis (TGA) and singlecrystal X- ray diffraction. Complex 1 crystallizes in the triclinic space group P - 1. The crystal structure consists of a dinuclear unit in which the Co (Ⅱ) ions are bridged by two azide ions in EO bridging mode. Magnetic susceptibility measurement of complex 1 showed weak ferrimagnetic exchange between the Co(Ⅱ) ions.
