我們成功利用低配位二價鐵金屬錯合物與一氧化氮反應，製備逆磁性之雙亞硝基鐵之胺基錯合物(DNICs)， Fe[N(Dipp)(R)]2(NO)2 (Dipp = 2,6- diisopropylaniline, R = TMS, Cy)，並完整鑑定其具有E-F notation為 {FeII(．NO)2}8 之中心電子組態。DNIC在光源刺激之下會產生一氧化氮的自身氧化還原反應而瓦解產生質子化配基與N2O，反應經由一分子NO的釋放而引發N-N鑑生成，最後產生N2O及質子化配基。利用電子循環伏安譜圖得知逆磁性之雙亞硝基鐵錯合物具有可逆的還原峰，並成功以化學方法還原一個電子生成具磁性之雙亞硝基鐵錯合物DNIC－，經過完整性質鑑定其中心電子組態為 {FeIII(－NO)2}9，在電子順磁共振光譜中於g = 2.016 有九根分裂的訊號；由於 NO－ 不容易從金屬中心解離的特性與熱催化之NO自身氧化還原反應速率減低之現象相符合，我們便利用還原方法而穩定具有巨大立體阻礙之DNIC，例如(Cp2Co){Fe[(Dipp)(SiMe2Ph)]2(NO)2}。
含有不同立體阻礙之配基的逆磁性雙亞硝基錳錯合物亦被成功製備且完整鑑定，而錳錯合物 {Mn[N(Dipp)(R)]2(NO)2}[A] (A = Li+(solvent)n或PPh4+) 則經由實驗證實為 {MnIII(－NO)2}8 之電子組態，並經由光源刺激後，同樣展現出NO自身氧化還原之反應。

Diamagnetic dinitrosyl iron complexes (DNICs) supported by various amido ligands were successfully synthesized through reactions of synthesized low coordinate iron(II) complexes with nitric oxide. The dinitrosyl iron complexes (DNICs), Fe[N(Dipp)(R)]2(NO)2 (Dipp = 2,6- diisopropylphenyl, R = SiMe3, c-C6H11), were characterized as diamagnetic complexes with {FeII(．NO)2}8 configuration. They decompose upon irradiation. From experimental data, the decomposition process can be rationalized as that NO dissociates from DNICs upon irradiation, attacks the bound nitrosyl ligands, and consequently results in NO disproportionation. The reactions of neutral DNICs with various reductants engender the formation of their anionic counterpart DNICs with {FeIII(－NO)2}9 electronic configuration. Characteristic 9-line-splitting around g = 2.016 for the said {FeIII(－NO)2}9 DNICs were observed from room temperature EPR spectroscopy. The observed slow NO disproportionation of anionic DNICs is consistent with the {FeIII(－NO)2}9 configuration in which NO‾ tends reluctantly to dissociate from the Fe centers.)
The dinitrosyl manganese complexes (DNMCs) [A]{Mn[N(Dipp) (R)]2(NO)2} (A = Li+(solvent)3 or PPh4+), could also be prepared from the reactions of corresponding Mn(II) amides with NO. An electronic configuration of {MnIII(－NO)2}8 was proposed form experimental data. NO disproportionation reactions were also observed when DNMCs were irradiated.
