报道了以四齿类席夫碱和双（4-吡啶基甲基）硫醚（bpms）为柔性桥接轴位配体的七种铁（II） 1D链配位聚合物的合成和表征。这种新材料在固体状态下表现出广泛的自旋转变特性，从渐变的，突然的，不完全的甚至是逐步的，这些特性都是用SQUID磁强计表征的。讨论了两种配合物在不同温度下的x射线结构分析。
The synthesis and characterisation of seven iron(II) 1D chain coordination polymers with tetradentate Schiff-base like equatorial ligands and bis(4-pyridylmethyl) sulfide (bpms) as a flexible bridging axial ligand is reported. This new family of materials displays a wide spectrum of spin transition properties in the solid state ranging from gradual, abrupt, incomplete to even step-wise that have all been characterized by SQUID magnetometry. The X-ray structure analysis of two complexes at several temperatures is discussed in the frame of their spin crossover properties.
