四甲基乙二胺（TMED，Me_2NCH_2CH_2NMe_2）与氯化钴（II）的存在下，在乙醚中的烷基锂的相互作用导致了四个配合物的分离，其晶体结构已被确定。配合物（TMED）CoR 2，R = CH_2SiMe_3和CH_2CMe_3，具有四面体的几何构型;在[（TMED）Li]_2 [Co（CH_2SiMe_3）_4]中，有CH_2SiMe_3基团桥接锂和钴原子;在离子型配合物[（TMED）_2Li][CoCl{CH（SiMe_3）_2}_2]中，具有三角平面的几何构型。电子顺磁共振光谱的配合物和与氧的反应的产物的报告。
The interaction of lithium alkyls in diethyl ether in the presence of tetramethylethylenediamine (TMED, Me2NCH2CH2NMe2) with cobalt(II) chloride has led to the isolation of four complexes whose crystal structures have been determined. The complexes (TMED)CoR2, R = CH2SiMe3and CH2CMe3, have tetrahedral geometry about cobalt; in [(TMED)Li]2[Co(CH2SiMe3)4] there are CH2SiMe3groups bridging the lithium and cobalt atoms; in the ionic complex [(TMED)2Li][CoCl{CH(SiMe3)2}2] the geometry about cobalt is trigonal planar. Electron paramagnetic resonance spectra of the complexes and of the products of the reaction with oxygen are reported.
