若干单核锰配合物的合成与表征

Synthesis and characterization of some new mononuclear manganese complexes

首次合成了三种单核锰配合物ＭｎＬ２１ＰｈＣＯＯ－，ＭｎＬ２２ＰｈＣＯＯＨ，ＭｎＬ２２ＨＡｃ．其中配体ＨＬ１，Ｈ２Ｌ２分别为三齿配体水杨醛缩邻苯二胺和水杨叉邻氨基酚；Ｐｈ为苯基．运用元素分析、化合价测定、电导率和磁化率测定、热重分析、ＩＲ、Ｕｖ－Ｖｉｓ、ＥＳＲ等方法对其性质进行了研究，提出了配合物可能的结构．

Three new mononuclear manganese complexes MnL 2 1·PhCOO -, MnL 2 2·PhCOOH, MnL 2 2·HAc were synthesized, and were also characterized by elemental analysis, determination valence, molar conductivity and electronic magnetic susceptibility, thermoanalyses, IR,Uv Vis,ESR spectra etc Possible structures of these complexes were brought out HL 1 and H 2L 2 represented salicylidene 1,2 phenylenediamine and salicylidene ortho hydroxyphenylamine respectively, both of which were tridentate ligands
