在四氢呋喃(THF)中,用Na砂还原四核双氮原子簇{[1,1-H10 C6(α-C4 H3 N)2]Sm}4(THF)2(μ-N2),得到了线性高分子二价Sm配合物{[1,1-H10 C6(α-C4 H3 N)2]2Sm[Na(THF)]2}n,其中每个Sm原子被四个η5-键合的吡咯环包围,从而使金属中心具有形式上的30电子构型。
Reduction of the tetranuclear dinitrogen cluster {[1,1-H10C6(α-C4H3N)2]Sm}4(THF)2(μ-N2) with Na sand in THF afforded the linear polymeric divalent Sm complex {[1,1-H10C6(α-C4H3N)2]2Sm[Na(THF)]2}n, where each samarium atom is surrounded by four η5-bonded pyrrolide rings, thus giving the metal center a formal 30-electron configuration.
