摘要：
The green title complex, [Co-2(CH3)(2)(C12H21N2Si)(2)], was obtained from bis{[mu-N-tert-butyldimethylsilyl-N-(pyridin-2-ylmethyl)amido]chloridocobalt(II)} and methyllithium in diethyl ether at 195 K via a metathesis reaction. The dimeric cobalt(II) complex exhibits a crystallographic center of inversion in the middle of the Co2N2 ring (average Co-N = 2.050 angstrom). The Co-II atom shows a distorted tetrahedral coordination sphere. The exocyclic Co-N bond length to the pyridyl group shows a similar value of 2.045 (4) angstrom. The exocyclic methyl group has a rather long Co-C bond length of 2.019 (5) angstrom.
