The air-stable hydrated Fe^II species [TTDPzFe(py)₂]⋅2H₂O (1; TTDPz = tetrakis(thiadiazole)- porphyrazinato dianion) is reproducibly obtained by reaction of the corresponding unmetalated species [TTDPzH₂] with the Fe^II salt (NH${}_4{)}_2$Fe(SO${}_4{)}_2$⋅6H₂O. Experimental interconnection between the bis-pyridine derivative 1 and the bis-adduct of known crystal structure [TTDPzFe(DMSO)₂] (2) and the desolvated complex [TTDPzFe] (3) has been observed possible, with the formation in the air from the latter of the hydrated species [TTDPzFe]⋅2H₂O (4). Reported here are the general properties of complex 1 accurately examined as a solid in terms of its physicochemical properties, in comparison with those of the phthalocyanine analog [PcFe(py)₂], in terms of the magnetic behavior examined via Mössbauer spectra and magnetic susceptibility measurements under specified experimental conditions over a large range of temperature (300-4 K).

空气稳定的水合 Fe ^II物质 [TTDPzFe(py) ₂ ]⋅2H ₂ O ( 1 ; TTDPz = 四(噻二唑)-卟啉二价阴离子) 通过相应的非金属化物质 [TTDPzH ₂ ] 与 Fe ^II的反应可重复获得盐（NH${}_4{）}_2$铁(SO3${}_4{）}_2$⋅6H ₂ O。双吡啶衍生物1和已知晶体结构的双加合物 [TTDPzFe(DMSO) ₂ ] ( 2 ) 和去溶剂化络合物 [TTDPzFe] ( 3 ) 之间的实验互连已被观察到是可能的，其中后者在空气中由水合物质 [TTDPzFe]⋅2H ₂ O ( 4 ) 形成。这里报告的是作为固体的配合物1的一般性质，与酞菁类似物 [PcFe(py) ₂相比，在其物理化学性质方面进行了精确检查。]，通过穆斯堡尔谱和磁化率测量在大温度范围（300-4 K）的指定实验条件下检查磁性行为。
