摘    要:通过模板法合成了一个新颍的Mn(Ⅲ)配合物,其混合配体由一无机盐阴离子和水杨醛席夫(Schiff)碱组成.分别用元素分析、红外光谱、X-射线单晶衍射等对该配合物进行了结构表征.标题配合物属正交晶系,Pbca空间点群.晶胞参数为:a=12.4478(8),b=13.7536(9),c=18.7800(12),V=3215.2(4)3,Z=8.锰(Ⅲ)离子与Schiff碱上的两个氮原子、三个氧原子和一个异硫氰酸根离子上一个氮原子的配位,具有扭曲的八面体六配位环境.两个Mn(Ⅲ)配位体通过氧桥联形成双核结构.两个最近的Mn(Ⅲ)原子之间的距离为3.554.

关 键 词:晶体结构  席夫碱  锰(Ⅲ)配合物  桥连

Abstract:A novel manganese(Ⅲ) complex incorporating an inorgnic anion and a salicylaldehyde Schiff base ligand(Mn(salen)(NCS)]2(sal = salicylaldehyde,en = ethylenediamine) has been prepared and structurally characterized by elemental analysis,IR spectra and X-ray diffraction.The Mn(Ⅲ) ion has a distorted octahedron al coordination environment with three nitrogen atoms,two oxygen atoms,among which one oxygen atom is from isothiocyanato ion.Two Mn(Ⅲ) complexes units were inter-linked into dimer via bridge-oxygen atoms,The distance between the nearest two Mn(Ⅲ) atoms is 3.554A.
Keywords:single crystal structure  Schiff base  manganese(Ⅲ) complex  bridge-linking
