合成新的鐵(II)-雙亞胺錯合物,組成為FeL_2 (NCS)_2,L代表雙配位座雙亞胺配位子;如N-環戊烷基-2-吡啶醛亞胺,N-環庚烷基-2-吡啶醛亞胺,與其6-甲基取代衍生物。其鐵(II)之基態電子自旋狀態由變溫梅思堡光譜及變溫磁化率測定加以探討。
The iron (II)-diimine complexes of the type [FeL_2(NCS)_2] have been prepared and characterized, where L denotes the bidentate diimine ligands; such as N-cyclopentyl-2-pyridinaldimine and N-cycloheptyl-2-pyridinaldimine and their 6- position methyl-substituted derivatives. The electronic ground spin-state of iron (II) in these complexes has been studied by means of Mossbauer spectroscopy and magnetic susceptibility measurements.
