The reaction of dimethyl sulfide (DMS) and tetrahydrothiophene (THT) with thin, amorphous layers of the nitrato complexes Fe(Por)(η-ONO) (Por = meso-tetraphenylporphyrinato dianion or meso-tetra- p-tolylporphyrinato dianion) at low temperature leads to formation of the corresponding six-coordinate complexes Fe(Por)(L)(η-ONO) (L = DMS, THT) as characterized by Fourier transform infrared and optical spectroscopy measurements. Adduct formation was accompanied by bidentate-to-monodentate linkage isomerization of the nitrato ligand, with the Fe center remaining in a high-spin electronic state. These adducts are thermally unstable; warming to room temperature restores the initial Fe(Por)(η-ONO) species.
低温下，二甲基硫（DMS）和四氢噻吩（THT）与硝酸根配合物 Fe(Por)(η-ONO)（Por = meso-四苯基卟啉二阴离子或 meso-四对甲苯基卟啉二阴离子）的非晶态薄层反应，生成相应的六配位配合物 Fe(Por)(L)(η-ONO)（L = DMS，THT），通过傅里叶变换红外和光谱光学测量进行了表征。加合物的形成伴随着硝酸根配体的双齿到单齿的键异构化，Fe 中心保持高自旋电子态。这些加合物热不稳定；升温至室温可恢复初始的 Fe(Por)(η-ONO)物种。
