and L2P, were synthesized. These ligands were used to form iron(II) complexes with an FeIITerpy2 core. Variable-temperature resonance Raman, UV–visible, and Mössbauer spectroscopies with magnetic measurements aided by density functional theory calculations were used to understand the physical characteristics of the complexes. By a comparison of measurements, the polymers were shown to behave in the
具有2,2':6',2''-吡啶(Terpy)侧基的两个新的环三磷腈配体,即(五苯氧基)4- [2,6-双(2-吡啶基)]吡啶氧基}环三磷腈(L 1)合成了(五苯氧基)4- [2,6-叔吡啶-4-基]苯氧基}环三磷腈(L 2),以及它们各自的聚合物类似物L 1P和L 2P。这些配体用于与Fe II Terpy 2形成铁(II)配合物。核。在密度泛函理论计算的帮助下,借助磁测量的变温共振拉曼光谱,紫外可见光谱和莫斯鲍尔光谱学被用来理解络合物的物理特性。通过测量比较,显示聚合物表现出与环三磷腈类似物相同的方式。结果表明,通过延长配体的间隔区长度至L 2和L 2P中的间隔区长度,可以诱导自旋交叉(SCO)在高温下开始。这种结合为形成可延展的SCO材料提供了一条途径。
