摘要
采用溶剂热的方法合成了配合物[Mn3^Ⅱ(PhCOO)4(phen)2(Ac)2](1)。通过X-射线单晶衍射、元素分析、X-射线粉末衍射和红外光谱的方法对其表征。其晶体属单斜晶系,P21/c空间群。晶胞参数:a=1.07699(15)nm,b=1.15416(16)nm,c=2.0360(3)nm,β=91.823(3)°,V=2.5295(6)nm^3,Z=2,F=1154。配合物1为三核结构,通过π…π堆积作用形成了二维结构。配合物1的变温磁化率研究表明,金属锰离子在2~300 K温度区间显示反铁磁性耦合。CCDC:955788。
A new complex [Mn3^Ⅱ( PhCOO)4( phen)2( Ac)2]( 1) was synthesized by solvothermal method and characterized by single-crystal diffraction,elemental analyses,powder X-ray diffraction and IR spectroscopy.The title compound crystallizes in the monoclinic system with space group P21/c,a =1.07699( 15) nm,b = 1.15416( 16) nm,c = 2.0360( 3) nm,β = 91.823( 3) °,V = 2.5295( 6)nm^3,Z = 2,F = 1154.Compound 1 is trinuclear.It is assembled into a 2D network structure throughπ… π staking interactions.Variable temperature( 2-300 K) magnetic studies for 1 indicate weak antiferromagnetic exchange interactions between metal centers.CCDC: 955788.
