Bis[?-N-(tert-butyl-dimethyl-silyl)-N-(pyridin-2-ylmeth-yl)amido]-bis-[methyl-cobalt(II)].

ABSTRACT: The green title complex, [Co(2)(CH(3))(2)(C(12)H(21)N(2)Si)(2)], was obtained from bis-{[?-N-tert-butyl-dimethyl-silyl-N-(pyridin-2-ylmeth-yl)amido]-chloridocobalt(II)} and methyl-lithium 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 Co(2)N(2) ring (average Co-N = 2.050?Å). The Co(II) atom shows a distorted tetra-hedral coordination sphere. The exocyclic Co-N bond length to the pyridyl group shows a similar value of 2.045?(4)?Å. The exocyclic methyl group has a rather long Co-C bond length of 2.019?(5)?Å.
