SC(C6H5)=N - CH(CO2C2H5) and diironhexacarbonyl (dimer) Fe2(CO)6 - SC(C6H5) - N=CH(CO2C2H5) complexes have been solved by direct methods. An interesting feature of the dimers is the short iron-iron distances (average distance : 2.58 A) which are consistent with a direct Fe-Fe interaction. Mossbauer parameters are characteristic of low spin iron II. Quadrupole splitting is related to the nature of the substituents
三羰基二铁(单体)Fe(CO)3-SC(C6H5)=N-CH(CO2C2H5)和六羰基二铁(二聚体)Fe2(CO)6-SC( )-N=CH(CO2C2H5)配合物的结构测定具有用直接方法解决。二聚体的一个有趣特征是短的铁-铁距离(平均距离:2.58 A),这与直接的 Fe-Fe 相互作用一致。穆斯堡尔参数是低自旋铁 II 的特征。四极分裂与取代基的性质有关。在 300 到 77 K 之间观察到微弱的温度无关顺磁行为。磁数据已与两级模型拟合。
