Air-sensitive complexes {Fe(NO)(2)}(9)-{Fe(NO)(2)}(9) Fe(mu-SC(6)H(4)-o-N(CH(3))(2))(NO)(2) (1), {Fe(NO)(2)}(9)-{Fe(NO)(2)}(10) Fe(mu-SC(6)H(4)-o-N(CH(3))(2))(NO)(2)(-) (2), the anionic {Fe(NO)(2)}(10) (SC(6)H(4)-o-N(CH(3))(2))Fe(NO)(2) (3), and the anionic {Fe(NO)(2)}(10)-{Fe(NO)(2)}(10) Fe(NO)(2)(mu-SC(6)H(4)-o-N(CH(3))(2))(mu-CO)Fe(NO)(2) (4) with mixed CO-thiolate-bridged ligands were synthesized. All complexes were characterized by IR, UV-vis, electron paramagnetic resonance, and single-crystal X-ray diffraction. The interconversions among these complexes were demonstrated. The interconversion between complexes 1 and 2 is accomplished by reduction and oxidation. Complex 3 adapts a {Fe(NO)(2)}(10) electronic structure with a N/S ligation mode and serves as a donor reagent of the {Fe(NO)(2)}(10) moiety. {Fe(NO)(2)}(10)-{Fe(NO)(2)}(10) complex 4 possesses the butterfly-like [Fe(mu-S)(mu-C)Fe] core with a shorter Fe...Fe distance of 2.5907(5) A attributed to the shorter Fe-S and Fe-C bond distances.
空气敏感配合物{Fe(NO)(2)}(9)-{Fe(NO)(2)}(9)Fe(mu-SC(6)H(4)-o-N(CH(3))(2))(NO)(2)(1)、{Fe(NO)(2)}(9)-{Fe(NO)(2)}(10)Fe(mu-SC(6)H(4)-o-N(CH(3))(2))(NO)(2)(-) (2)、阴离子{Fe(NO)(2)}(10)(SC(6)H(4)-o-N(CH(3))(2))Fe(NO)(2) (3)和阴离子{Fe(NO)(2)}(10)-{Fe(NO)(2)}(10)Fe(NO)(2)(mu-SC(6)H(4)-o-N(CH(3))(2))(mu-CO)Fe(NO)(2) (4)，这些配合物都具有混合的 CO-硫醇桥连配体。所有的配合物都通过红外、紫外可见、电子顺磁共振和单晶 X 射线衍射进行了表征。证明了这些配合物之间的相互转化。配合物 1 和 2 之间的相互转化是通过还原和氧化完成的。配合物 3 采用{Fe(NO)(2)}(10)的电子结构和 N/S 配体模式，作为{Fe(NO)(2)}(10)部分的供体试剂。{Fe(NO)(2)}(10)-{Fe(NO)(2)}(10)配合物 4 具有蝶形[Fe(mu-S)(mu-C)Fe]核，Fe...Fe 距离为 2.5907(5)A，这归因于较短的 Fe-S 和 Fe-C 键距离。
