Abstract
The first iron(ii) complex of 2,5-di-(2-pyridyl)-1,3,4-thiadiazole (L), namely [Fe(II)(L)(2)(NCS)(2)], has been synthesised and studied by magnetic susceptibility measurements, Mössbauer spectroscopy and X-ray diffraction. It has been found to undergo thermally-induced spin crossover featuring two well-separated, abrupt steps at T(1/2)(1) = 167 K and T(1/2)(2) = 112 K.
摘要
首个 2,5-二（2-吡啶基）-1,3,4-噻二唑（L）的铁（II）配合物，即[Fe（II）（L）（2）（NCS）（2）]，已通过磁化率测量、穆斯堡尔光谱和 X 射线衍射进行了研究。发现其具有热诱导自旋交叉特性，在 T(1/2)(1) = 167 K 和 T(1/2)(2) = 112 K 处有两个明显的、急剧的分离步骤。
