Abstract Iron(III) halides on reaction with 3,6-disubstituted-2,7-dihydro-1,4,5-thiadiazepine derivatives (L) form complexes of the general formula FeL2X3·nH2O (X = Cl,.Br, n = 1.5, 4, 5; L = L-1, L-2, L-3 and L-4 for substituent R in para position of Ar group as H, CH3, Cl and OCH3 respectively). These complexes were characterized by elemental analysis, IR, far-IR, ESR, electronic, 1H NMR and Mossbauer
摘要卤化铁(III)与3,6-二取代-2,7-二氢-1,4,5-噻二氮杂衍生物(L)反应形成通式为FeL2X3·nH2O的配合物(X = Cl,.Br,n在Ar基团对位的取代基R分别为H,CH 3,Cl和OCH 3 == 1.5、4、5; L = L-1,L-2,L-3和L-4)。这些配合物通过元素分析,IR,远红外,ESR,电子,1H NMR和Mossbauer光谱,磁矩,摩尔电导,tga和dta数据进行表征。数据支持阳离子[FeX2L4] +的八面体结构,其中L充当未知配体(通过氮原子配位),而阴离子[FeX4]-则为四面体结构。所有复合物都是顺磁性的,在室温下的μeff值在5.84–6.15 BM范围内。热学研究和红外光谱表明存在未配位的水。
