), as well as some heteroleptic metallates, such as [Li(OEt2)2][Sn(n)BuHyp2] (3d), [Li(OEt2)2][Pb(n)BuHyp2] (4d), [Li(thf)4][PbPhHyp2] (3e), and [K(thf)7][PbHyp2N(SiMe3)2}] (3f), were synthesized and crystallographically characterized. Through oxidation by tin(II) and lead(II) bis(trimethylsilyl)amides or the related 2,6-di-tert-butylphenoxides, they had been oxidized to yield in most cases the corresponding
在这份报告中,我们介绍了合成,晶体学和新的电子顺磁共振(EPR)光谱学工作,这些工作表明合成途径导致了最近报道的第一个持久性铅基自由基* PbEbt3(Ebt =乙基双(三甲基甲硅烷基)甲硅烷基),即相关的PbEbt3-阴离子的氧化很容易扩展到铅和锡的其他持久性分子单核自由基的合成。首先,均化金属钾盐KSnHyp3(4a),KPbHyp3(3a),KSnEbt3(4b),KPbIbt3(3c)和KSnIbt3(4c)的各种新型溶剂化物(Hyp =三(三甲基甲硅烷基)甲硅烷基,Ibt =异丙基双(三甲基硅烷基)甲硅烷基甲硅烷基),以及一些杂配金属盐,例如[Li(OEt2)2] [Sn(n)BuHyp2](3d),[Li(OEt2)2] [Pb(n)BuHyp2](4d),[Li (thf)4] [PbPhHyp2](3e)和[K(thf)7] [PbHyp2 N(SiMe3)2}](3f)
