摘要
水热法合成了一个基于1,4-苯二硫乙酸(H2L)柔性配体的Mn(Ⅱ)配合物[Mn3L3(phen)2]n,并通过元素分析,红外光谱、热失重和X-射线单晶衍射实验对其结构进行了表征。结构分析表明,配合物是一个包含三核锰结构单元的二维层面结构。对配合物的变温磁化率研究表明,在三核锰离子间存在弱的反铁磁交换作用。
A new Mn(Ⅱ) complex based on 1,4-benzenebis(thioacetic acid)(H2L),[Mn3L3(phen)2]n(1,phen=1,10-phenanthroline),has been hydrothermally synthesized and characterized by single crystal X-ray diffraction,elemental analysis,IR spectrum,and TG analysis.The structure can be considered as a two-dimensional(2D) layered architecture which consists of linear trinuclear Mn(Ⅱ) units.The magnetic susceptibility data are interpreted with the linear trinuclear law,yielding J and g values of -1.95(5) cm^-1 and 1.98(1).The exchange integral(J) indicates a weak antiferromagnetic interactions in the linear trinuclear Mn(Ⅱ) unit.CCDC:734943.
